镍基合金重熔层热强度研究

Study of the Hot Strength of Remelted Ni-based Alloy Coating

研究配制5种类型的镍合金粉末,及其喷涂重熔后的硬度随温度上升的变化规律,并进行了热疲劳试验,通过研究优化出一种适于高温耐磨强化的合金。

Tthe changing rule of the hardness of remelted Ni-based alloy hot spraying coating with temperature was studied with 5kinds of Ni-based alloy powder asmple. Hot fatigue test was made. A knd of alloy waw optimized as high temperature wear proof alloy.
