Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the redrafting method to modify the use of ISO 14923.2003 "characterization and testing of thermal spray coatings." The technical differences between this standard and ISO 14923.2003 and their reasons are as follows. --- For ease of use, the normative reference documents have been technically adjusted to suit the technical conditions of China, and the set of adjustments Reflected in Chapter 2, “Regulatory Citations,” Appendix A gives specific adjustments to normative references. According to the table. This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Standardization of Metal and Non-Metallic Coatings (SAC/TC57). This standard was drafted. Wuhan Material Protection Research Institute Co., Ltd., Jiangsu Zhongzheng Dazheng Surface Engineering Technology Co., Ltd., Foshan Advanced Surface Technology Co., Ltd., Jiangxi Hengda High-tech Co., Ltd., Tongxiang Tiesheng Line Equipment Co., Ltd., Wuhan Xinhuafeng Machinery Manufacturing Co., Ltd.

Characterization and test of thermal spray coating

1 Scope

This standard provides guidance on the characterization and testing of thermal spray coatings. Since all fusible materials can be used for thermal spraying, there are many The same thermal spray process, there are a large number of different types of coatings, so it is impossible to specify all the coatings in this standard. This standard lists the general test methods and test specifications for thermal spraying. This standard does not address only certain situations or experiments. Test method carried out under room conditions. Note. This standard does not cover all methods.
