一种进气门座粉末冶金制备方法
摘要：
本发明公开了一种进气门座粉末冶金制备方法，包括有以下步骤：配置混合粉末原料，混合粉末原料由如下重量百分比的粉末原料组成:Cu 4-5%、Mn 4-5%、Ni 0.8-1.2%、Co 0.5-0.8%、MoS2 0.5-0.6%、Pb 0.6-1.2%、有机硅树脂粘合剂1.6-2.2%，Y2O3 0.15-0.18%，余量为基料不锈钢粉末,混料后再磨制成颗粒粒径250-300微米的粉末；本发明在原料配方中加入不同比例的金属粉末，使得制备出的进气门座达到高强度，高硬度和高扭矩的性能。
摘要（英）：

The invention discloses a power metallurgy preparation method for intake valve seats. The method comprises the following steps: a mixed powder raw material is prepared, the mixed powder raw material comprises the following powder raw materials: by weight percentage, 4%-5% of Cu, 4%-5% of Mn, 0.8%-1.2% of Ni, 0.5%-0.8% of Co, 0.5%-0.6% of MoS2, 0.6%-1.2% of Pb, 1.6%-2.2% of organic silicon resin adhesive, 0.15%-0.18% of Y2O3 and the balance basic material stainless steel powder, and after the materials are mixed, the mixed powder raw material is grinded into powder with the particle diameter of 250-300 [mu]m. In the method, metal powder of different proportions is added according to a raw material formula so that the prepared intake valve seats can achieve the properties of high intensity, high hardness, and high torque.
