Abstract

We have studied the effect of discharge pulse duration in the electrospark deposition process on the structure and properties of FeCrWMoCB metallic glass coatings. The coating thickness has been shown to rise from 19.1 to 39 μm with increasing pulse duration. The heat resistance of the coated samples over 100 h of testing at 700°C was 27 to 176 times that of the steel and it increased with increasing pulse duration. The hardness of the coatings ranged from 11.3 to 11.9 GPa. The coatings have been shown to reduce the friction coefficient and wear of the steel by a factor of up to 3.7 and improve its corrosion resistance.

放电持续时间对 FeCrWMoCB 金属玻璃镀膜特性的影响

摘要--我们研究了电火花沉积过程中放电脉冲持续时间对 FeCrWMoCB 金属玻璃涂层结构和性能的影响。随着脉冲持续时间的增加，涂层厚度从 19.1 微米增加到 39 微米。在 700°C 下测试 100 小时，涂层样品的耐热性是钢的 27 至 176 倍，并且随着脉冲持续时间的增加而增加。涂层的硬度范围为 11.3 至 11.9 GPa。涂层可将钢的摩擦系数和磨损降低 3.7 倍，并提高其耐腐蚀性。
