4、ic sprayed coatings H 8304-1994 1. This Japanese Industrial Standard specifies the significant surface( l) of the ceramic sprayed coatings (hereafter referred to as “coatings“) applied for the purpose of giving wear resistance, chemical resistance, heat resistance, heat insula- tion, etc. to parts,
5、products, etc. Scope Note (l) The significant surface herein means the surface important to the use of the product. Remarks 1. The ceramic thermal spraying means which is carried out with plasma spraying, powder flame spraying, or rod flame spraying by using ceramics having metal oxides such as alum
6、inium oxide, chromium oxide, titanium oxide, zirconium oxide, etc. as main components. The following standards are cited in this Standard.
