复合陶瓷挺柱由于其优越的耐磨与减磨性能而成为取代现有合金挺柱的最佳材料 ,尤其是在使用条件苛刻的发动机中。钎焊质量是影响复合陶瓷挺柱使用性能的关键因素之一 ,因此如何保证与控制钎焊质量是复合陶瓷挺柱进入实际应用的前提。而影响挺柱使用性能并与钎焊相关的是钎着率和钎焊引起的变形。本文从控制复合陶瓷挺柱的钎焊质量出发 ,试验研究了影响钎焊钎着率和焊后变形的各种因素和规律 ,得到了有实际意义的结论 Composite ceramic tappet is the best material to replace the existing alloy tappet due to its excellent wear and abrasion resistance, especially in engines with harsh conditions of use. Brazing quality is one of the key factors that affect the performance of composite ceramic tappet. Therefore, how to guarantee and control the quality of brazing is the prerequisite for the application of composite ceramic tappet. And affect tappet performance and brazing is related to the brazing rate and the deformation caused by brazing. In this paper, starting from controlling the brazing quality of the composite ceramic tappet, various factors and rules that affect the brazing rate and post-weld deformation have been experimentally studied, and practical conclusions have been obtained
