Corrosion Protection Performance Testing for Boiler Film Formation Samples

Electrochemical impedance spectroscopy for film barrier properties per ASTM G106 — the filmed boiler metal sample is immersed in simulated boiler water and the impedance spectrum is measured to quantify the pore resistance, capacitance, and barrier performance of the protective film, providing a non-destructive assessment of corrosion protection effectiveness.
Linear polarization resistance and corrosion rate measurement per ASTM G59 and ASTM G102 — the instantaneous corrosion rate of the film-covered boiler metal is measured in simulated boiler water to quantify the reduction in corrosion current provided by the film-forming amine treatment.
Potentiodynamic polarization testing per ASTM G5 and ASTM G61 — the anodic and cathodic polarization behavior of the filmed boiler sample is characterized to determine the corrosion potential, passivation current density, and the breakdown potential of the protective film.
Neutral salt spray and humid cabinet corrosion testing per ISO 9227 and ASTM D2247 — the filmed boiler metal specimens are exposed to salt fog and high-humidity conditions to evaluate the film's ability to protect against atmospheric corrosion during boiler layup and shutdown periods.
High-temperature autoclave corrosion testing per ASTM G146 and internal protocols — the film formation sample is exposed to simulated boiler water at elevated temperature and pressure in an autoclave, and the corrosion rate and film stability are measured under the most representative boiler operating conditions.
Erosion-corrosion resistance testing per ASTM G73 and internal protocols — the filmed boiler tube specimen is subjected to a high-velocity water or wet steam flow to evaluate the film's resistance to erosion-corrosion in two-phase flow regions of the boiler and feedwater system.

Film Uniformity, Thickness, and Morphology Characterization

Film thickness measurement by ellipsometry and X-ray photoelectron spectroscopy depth profiling per ASTM E2389 and ASTM E1078 — the thickness of the protective film formed on the boiler metal surface is measured to verify the film-forming amine treatment produces a uniform, complete coverage with the specified film thickness for effective corrosion protection.
Scanning electron microscopy and energy dispersive X-ray spectroscopy per ASTM E1508 — the surface morphology and elemental composition of the boiler film formation sample are imaged at high magnification to verify the film is continuous, adherent, and free from defects, pinholes, or uncoated areas.
Atomic force microscopy for surface topography and roughness per ISO 25178 — the nanoscale surface roughness and film uniformity are measured to characterize the film quality and to detect any localized film breakdown or incomplete coverage on the boiler metal.
Fourier transform infrared spectroscopy for film chemical identification per ASTM E1252 — the infrared spectrum of the film is acquired to confirm the presence of the film-forming amine and to detect any oxidation products, contaminants, or degradation of the protective layer.
Contact angle and hydrophobicity measurement per ASTM D7334 — the water contact angle on the filmed boiler surface is measured to verify the film-forming amine has produced the expected hydrophobic surface that repels water and promotes dropwise condensation on condenser tubes.
Film coverage and porosity evaluation by copper sulfate spot test and ferroxyl test per ASTM A967 — the filmed boiler metal sample is tested with chemical spot indicators to detect any bare metal areas or film porosity that would allow localized corrosion to initiate.

Adhesion and Mechanical Stability Testing for Boiler Film Formation Samples

Cross-cut and tape adhesion testing per ISO 2409 and ASTM D3359 — the adhesion of the protective film to the boiler metal substrate is tested by scribing and tape peeling to verify the film remains firmly attached under mechanical stress and thermal cycling.
Bend and deformation adhesion testing per ASTM D522 and ISO 1519 — the filmed boiler metal specimen is bent around a mandrel to evaluate the film's ability to deform with the substrate without cracking or spalling, simulating the thermal expansion and contraction of boiler tubes.
Scratch adhesion testing per ASTM C1624 and ISO 20502 — a diamond stylus is drawn across the filmed surface under increasing load, and the critical load at which the film detaches is recorded to quantify the practical adhesion of the boiler protective film.
Impact resistance and film integrity after mechanical shock per ASTM D2794 and ISO 6272-2 — the filmed specimen is subjected to controlled impacts and the film is inspected for cracking, flaking, or detachment that would compromise corrosion protection in service.
Abrasion and erosion resistance of the protective film per ASTM D4060 and internal protocols — the filmed boiler surface is subjected to controlled abrasive wear and the loss of film mass is measured to predict the film's durability under the erosive conditions of high-velocity boiler water and steam flow.

Thermal Stability and High-Temperature Performance Testing for Boiler Film Formation Samples

Thermogravimetric analysis and differential scanning calorimetry per ASTM E1131 and ISO 11357-3 — the thermal decomposition profile of the film-forming amine and the protective film are measured to determine the maximum temperature at which the film remains stable, ensuring compatibility with the boiler operating temperature range.
High-temperature autoclave film stability testing per ASTM G146 — the boiler film formation sample is exposed to superheated water and steam at the maximum rated boiler temperature and pressure, and the film integrity, thickness, and corrosion protection are evaluated after defined exposure periods.
Thermal cycling and thermal shock per IEC 60068-2-14 — the filmed boiler metal specimen is rapidly cycled between hot and cold conditions to verify the film withstands the thermal expansion and contraction stresses of boiler start-up and shutdown cycles without cracking or delamination.
Steam exposure and wet-dry cycling resistance per internal protocols — the film formation sample is subjected to alternating steam and wet conditions to simulate the two-phase flow environment of the boiler and to evaluate the film's resistance to degradation under cyclic wetting and drying.
Long-term thermal aging and film degradation assessment per ASTM D573 — the filmed specimen is aged at elevated temperatures in a simulated boiler water environment, and the change in film thickness, adhesion, and corrosion resistance is measured to predict the service life of the protective film.

Chemical Composition and Film-Forming Amine Analysis

Film-forming amine concentration in boiler water by liquid chromatography-mass spectrometry per internal validated protocol — the concentration of octadecylamine, oleylamine, or other film-forming amines in the boiler water is quantified to verify the dosing rate and to correlate the water chemistry with the film quality on the boiler metal surfaces.
Film composition and thickness by X-ray photoelectron spectroscopy per ASTM E1078 — the elemental composition and chemical bonding states of the film are determined to verify the film-forming amine has reacted with the boiler metal surface to form the expected protective layer.
Degradation products and oxidation by-products analysis by gas chromatography-mass spectrometry — the boiler water and film extracts are analyzed for degradation products of the film-forming amine to detect any thermal decomposition or oxidation that would reduce the corrosion protection effectiveness.
pH, conductivity, and total organic carbon of boiler water per ASTM D1293 and ASTM D5997 — the boiler water chemistry parameters are measured to ensure the film-forming amine treatment is compatible with the overall water treatment program and does not cause foaming, carryover, or deposition in the steam-water cycle.
