摘要
研究了不同淬火冷却方式、不同表面强化处理工艺对镁合金压铸模具的表面硬度、耐磨损性、耐高温腐蚀性和渗层深度的影响。结果表明,淬火分级冷却比普通油冷、离子氮化后再固体渗钒-稀土钇的复合强化热处理比普通离子氮化处理,均明显提高了模具的耐磨性和耐高温腐蚀性,在镁合金压铸模具热处理中具有较强的实用性。
The effects of different cooling methods of quenching and surface strengthening processes on the surface hardness, wear resistance, corrosion resistance at high temperature and layer depth of magnesium alloy die-casting die samples were studied. The results show that in comparison with common oil cooling and ion nitriding, grade cooling of quenching and combined strengthen heat treatment which was solid vanadinizing with rare earth yttrium after ion nitriding, can effectively improve the wear resistance and corrosion resistance at high temperature of magnesium die-alloy casting die. The grade cooling of quenching and combined strengthen heat treatment have stronger practicability.
