4、 12 Clause 1 of the Industrial Standardization Law. Cermet thermal spraying has been mostly utilized in various industrial equipments for the purpose of wear resistance, chemical corrosion resist- ance, heat resistance, thermal insulation and the like, for instance, in the mechanical parts and so on
5、 for iron and steel, textile, paper manu- facture. This Japanese Industrial Standard has been established based on the request of standardization of cermet thermal spraying to JIS under the background of such situation.

12、tted without license from IHS -,-,- JAPANESE INDUSTRIAL STANDARD JIS H 8306 : 2002 Cermet thermal spraying 1 Scope This Japanese Industrial Standard specifies the effective surface(1) of cermet thermal spraying coating (hereafter referred to as “coating”) performed for the pur- pose of giving wear r
13、esistance, chemical corrosion resistance, heat resistance, ther- mal insulation and the like to parts, products and so on. Note (1) The important surface for use. Remarks : Cermet thermal spraying means that coating is formed by a plasma spraying method or a powder flame spraying method by the powde
14、rs (composed of plural inhomogeneous phases) of high hardness and me- tallic property which are obtained by combining oxide, carbide, ni- tride, boride or silicide with metal. 2 Normative references The following standards contain provisions which, through reference in this Standard, constitute prov
15、isions of this Standard. The most recent editions of the standards (including amendments) indicated below shall be applied.
