GB/T 11373-2017Thermal spraying - Pre-treatment of surfaces of metallic parts and components (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 11373-1989 "Thermal Sprayed Metal Parts Surface Pretreatment General," compared with GB/T 11373-1989 main Technical differences are as follows:

--- Complement the surface pretreatment method;

--- Supplementary preheating requirements;

--- Complement the non-painted area of the shelter requirements;

--- Supplementary pretreatment on the impact of fatigue strength analysis. This standard is proposed by the China Machinery Industry Federation. This standard by the National Metal and Nonmetallic Coating Standardization Technical Committee (SAC/TC57) centralized. This standard was drafted. Wuhan Institute of Materials Protection, Jiangsu Zhongzheng Dazheng Surface Engineering Co., Ltd., Ma On Shan Dingtai Rare Earth New Materials Co., Ltd., Foshan Advanced Surface Technology Co., Ltd., Tongxiang Tiensheng Line Equipment Co., Ltd., Wuhan University of Technology, Shengli Oil Tianxin large tube technology development limited liability company, Dongying Yellow River Delta standard technical service center, Shenzhen Kechuang standard service center.

1 Scope

GB/T 11373-2017 is the Chinese national standard on thermal spraying - pre-treatment of surfaces of metallic parts and components, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 September 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 April 2018. Classification: ICS 25.220.10, CCS A29. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the thermal spraying of metal parts surface pretreatment process, a clear surface thermal spraying metal parts should be pre-treatment Important principles to consider. This standard applies to the production of new parts, but also for the repair of old parts. For corrosion-resistant thermal spraying zinc, aluminum and its alloy coating see GB/T 9793.
