This Standard replaces GB/T 9793-1997 "Metallic and other inorganic coatings - Thermal spraying - Zinc, aluminium and their alloys". Compared with GB/T 9793-1997, the main changes of this Standard are as follows: - Update all reference documents; - Delete some national standards and machinery industry standards cited in GB/T 9793-1997; - Delete the explanation of "measurement surface", "reference surface" and "local thickness" in "Terms and definitions"; - Add two preparation abrasives, "copper refinery slag" and "coal furnace slag" in 6.1; - Delete "Result interpretation" in annex A.1.4; - Add part of annex A.2 "Tensile test". This Standard, using translation method, is identical to ISO 2063:2005 "Thermal spraying - Metallic and other inorganic coatings - Zinc, aluminium and their alloys". China’s documents which have a consistent correspondence with the international documents normatively referenced in this Standard are given in annex NA. This Standard has made the following editorial change: - Add an informative annex NA, China’s documents which have a consistent correspondence with the international documents normatively referenced in this Standard.

Thermal spraying - Metallic and other inorganic coatings - Zinc, aluminum and their alloys1 ScopeThis Standard applies to thermal-sprayed metallic coatings for the protection of iron and steel against corrosion by applying zinc or aluminium or their alloys to uncoated surface to be protected. This Standard deals with characteristic properties and gives test methods for coatings obtained by the spraying of zinc and aluminium and their alloys for the general purpose of corrosion protection. This Standard gives firstly the definition, classification and symbols for these coatings in relation to their thickness. It then deals with the preparation of surfaces, application of coatings and their characteristic properties: namely, thickness, appearance and adhesion. Finally it gives test methods for checking these properties. For other metals some of the provisions are valid and can be adopted by agreement between the interested parties.2 Normative referencesThe following documents are indispensable for the application of this document.
