GB/T 11373-1989
AbolishedThe general principle of surface preparation of metallic substrate for thermal spraying
热喷涂金属件表面预处理通则
Application Summary AI generated
This standard specifies the general principles and requirements for cleaning, roughening, and activating the surface of metallic substrates prior to thermal spraying. It is applied in manufacturing industries where thermal spray coatings are used for wear resistance, corrosion protection, or dimensional restoration, such as in aerospace, automotive, and heavy machinery components. The standard ensures proper adhesion of sprayed coatings by defining acceptable surface cleanliness, roughness profiles, and preparation methods.
