陶瓷合金浸蚀特性的研究

Study on the features of erosion of cermets

为了研究不同成分、组织及性能的陶瓷合金的耐浸蚀磨损性能,采用了0.1～0.3mm碳化硅和二氧化硅磨粒浸蚀剂,撞击角度为30°～90°,撞击速度为30～80m/s,对8种陶瓷合金靶材试样进行了浸蚀试验。此外,还用多普勒风速计测量技术来研究固体磨粒浸蚀剂对陶瓷靶材试样相互作用的过程,系统研究了撞击变量变化对撞击过程的影响。

The erosion-resisting and wearproof of cermets with different composition,structure and properties were investigated.In this paper,solid particle erosion test on eight materials have been performed using silicon carbide and silica abrasive particles within a range of erodent size of 0.1～0.3?mm,impact angles from 30°to 90°and particle velocity from 30 to 80? m/s .The process of interaction of solid particles with cermet targets was studied using doppler anemometer measuring technique.Systematic study on the influence of the impact variables on the collision process has been carried out.
