摘　　要：通过热喷涂等技术将金属基陶瓷复合粉末熔覆于渐进式安全钳楔块表面，制成了兼具金属材料和陶瓷材料特性的涂层楔块。这样，在不改变其他影响因素的前提下。改变了安全钳摩擦副配对材质，进而提高了原基体楔块的各项物理性能和制动效果。在此基础上进行了球墨铸铁和45号钢涂层前后楔块比对试验研究，从平均减速度．制停距离和摩擦系数的变化分析了其摩擦制动性能的改善情况。By the thermal spraying technology, the research will make the clad metal base ceramic composite powder in the wedge block surface of progressive safety gear, made of coating wedge combining the characteristics of metal material and ceramic material. So as to change matching material of the friction pair of safety gear, and improve all the physical properties and braking effect of the original matrix wedge block without changing other influence factors. Final, through a series of wedges＇ comparison test research before-after coating between nodular iron and No.45 steel, this article would analyze improved results of friction braking performance from average deceleration, stopping distance and friction coefficient.
