	1.HDM钢热处理工艺研究作者：刘树勋，李培杰，曾文本摘要：通过选择不同固溶、时效温度组合，对新型镁合金压铸用模具钢（HDM）的组织及性能和热处理工艺之间的关系进行了详细的探讨，确定出HDM钢最佳固溶时效热处理工艺为（1100±10）℃×1h+（700+10）℃×2h。关键词：热琢模具钢；热处理，压铸 Abstract：Choosing different solution temperature and ageing temperature,effects of heat treatment process on the microstructure and mechanical properties of a new type of steel HDM for magnesium die casting have been studies in details. Based on these studies, a optimum heat treatment process was determined, which is solution-treated at 1100℃ for 1h and aged at 700℃ for 2h. 摘自《金属热处理》2002年第五期
	2.热等离子弧对钢表面淬硬深度的影响作者：赵程，田丰，侯俊英摘要：有3种连接方式可以用于等离子弧的表面淬火工艺：转移弧、非转移弧和联合弧。本文对比了这3中连接方式的等离子弧对表面淬硬深度的影响。试验结果表明，转移弧和联合弧的加热效率比较高，可以获得比非转移弧更深的淬硬深度。但小口径的非转移弧或联合弧的电弧燃烧稳定，比较适合于等离子弧淬火处理。关键词：等离子弧；淬硬深度 Abstract：There were three connection methods of therma1 plasma arc, which were transferred arc, non-transferred arc and comined arc. The effects of different connection methods of thermal plasm arc on hardening dePth of stee1 were studied. The exPerimental results shoW that transferred arc and comined arc have higher heating effi-ciency and larger hardening depth comared with non-transferred arc. But the arc stability of the comined arc and non-transferred arc with smaller orifice diameter is higher than that of transferred arc, and they are more suitable for the hardening treatment by p1asma arc. 摘自《金属热处理》2002年第五期

The appearance, hardness and structure were analyzed and wear tests on a ring-on-block wear testing machine under lubrication were carried out. The addition of nano--diamond improved the hard-ness and wear resistance of composite coatings. The maximurn hardness and wear resistance could be obtained when the thickness of composite coating reached 27μm. 摘自《金属热处理》2002年第六期

The result indicated that the pulse electric current can homogenize structure of Q235 stee1, as the increase of pulse voltage and pulse frequency, the homogenization effect is enhanced.
