"GB/T 26110-2010 Technical Conditions for Zinc-Aluminum Coatings" standard specifies the technical requirements and test methods for applying zinc-aluminum coatings on steel parts and components. The standard is applicable to the surface protection of a variety of materials including cast iron, aluminum and its alloys, iron-based powder metallurgy, etc. The standard describes in detail the requirements of the preparation method of coatings, adhesion strength test, coating thickness measurement and corrosion resistance performance evaluation. Through this standard, the application effect of zinc-aluminum coatings on different substrates can be guaranteed, and standardized test methods and technical parameters are provided, which promotes the control and improvement of coating mass.
