柴油机气门堆焊层的性能和车削刀具研究

Study of the Lathe Tools and Cutting Characteristic for Weld Deposit Metal on the Valve in the Diesel Engine

柴油机气门锥面直接与高温燃气接触,工作条件恶劣,因此气门锥面需堆焊司太立合金。针对司太立合金堆焊工艺,分析了组织的性能,介绍了刀具材料及刀具形状的选择。

Because of the directly touch of the incline surface on value in diesel and high temperature gas, serious work environment. So we must weld the satellite metal to the incline of value. We can analyze the cutting characteristic of stellite metal. The article main introduce how to select material and figure of cutting tools.
