爆炸喷涂WC-Co涂层结合强度的测量方法及喷涂工艺研究
Method of Adhesion Strength and Spray Techniques of
Detonation Gun Sprayed WC-Co Coatings
摘要
Abstract
A new method has been introduced to measure the adhesion strength of the d-gun sprayed WC-Co coatings. The pulling critical size has been analyzed. The experiments show that the pulling critical size is about 2mm for detonation-spraying gun made in China and the adhesion strength for WC-Co coating is as high as 143MPa. It has indicated that the value of O2/C2H2 mol ratio must be 1.5 in order to avoid the oxidation of Co during spraying and obtain good microstructure.关键词
