Importance of Thermal Spraying

Thermal spraying is a versatile coating process used to apply materials onto surfaces to enhance their properties, such as wear resistance, corrosion protection, and thermal insulation. The process involves the deposition of molten or semi-molten materials onto a substrate, forming a coating that can withstand extreme conditions.

Applications of Thermal Spray Coatings

Thermal spray coatings are utilized across a wide range of industries, including:

• Aerospace: Protecting engine components from high temperatures and wear.
• Automotive: Enhancing the durability of engine parts and exhaust systems.
• Oil and Gas: Providing corrosion resistance to pipelines and offshore structures.
• Power Generation: Improving the efficiency and lifespan of turbines and boilers.

Understanding the Tubular Coating Tensile Test

The tensile test for tubular coatings, as outlined in the BS EN 17393:2020 standard, is a crucial procedure for assessing the mechanical properties of coatings. This test helps determine the coating's ability to withstand tensile forces, which is vital for ensuring its performance in real-world applications.

Why Conduct a Tensile Test?

Conducting a tensile test on tubular coatings provides valuable insights into:

• Adhesion Strength: Evaluating the bond between the coating and the substrate.
• Elasticity: Measuring the coating's ability to deform under stress without breaking.
• Durability: Assessing the coating's resistance to mechanical wear and tear.

• 25.220.20 Surface treatment

This document specifies the procedure for the determination of coating strength, and hence of cohesive strength in a tubular coating tensile test. The test is intended to determine the tensile coating strength parallel to the spray layers (normal to the spray direction) and to identify differences in particle cohesion quality, as caused by defects as internal delamination at cracks or oxides between the spray particles or splats. The tubular coating tensile test is suitable for sprayed coatings deposited using metallic materials (not carbides and ceramics). The tubular coating tensile test is not suitable for fused sprayed coatings deposited using self-fluxing alloys. The test supports quality assurance and is intended to be applied for the purpose of coating optimization by identifying the influences of coating parameters and spray materials on the coatings's quality. Furthermore, the coating in particular for cold sprayed coatings can be compared with the characteristics of similar solid materials and the coating's quality can be assessed. This test is not recommended for thin coatings (coating thickness < 500 µm), since massive scattering of results is to be expected here. Due to the size of the specimen, it is particularly suitable to apply the tubular coating tensile test for coating processes that use a concentrated spray jet and a highly focused spray spot, as in the case of cold spraying, high velocity flame spraying (HVOF) or plasma spraying. Applying the tubular coating tensile test for coating processes that use a broad spray jet, such as flame spraying and arc spraying, may require special spraying measures, e.g. the use of a template to ensure a nearly vertical impingement angle.
