用于形成金金属基体复合材料的方法和装置
摘要：
本发明涉及用于形成金金属基体复合材料的方法和装置。提供了使用贵金属作为组分之一的金属基体复合材料。在一个实施方案中，贵金属采取金的形式并且金属基体复合材料具有与18k一致的金质量分数。通过混合贵金属(例如金)粉末和陶瓷粉末形成混合物、随后在具有金属基体复合材料的近终形的模具内将该混合物压缩，可形成金属基体复合材料。随后将模具中压缩的混合物加热以烧结贵金属和陶瓷粉末。还公开了使用HIP和金刚石粉末形成贵金属基体复合材料的其它技术。
摘要（英）：

The invention relates to a method and apparatus for forming a gold metal matrix composite. The metal matrix composite using as one of the components a precious metal is described. In one embodiment, the precious metal takes the form of gold and the metal matrix composite has a gold mass fraction in accordance with 18k. The metal matrix composite can be formed by blending a precious metal (e.g., gold) powder and a ceramic powder, forming a mixture that is then compressed within a die having a near net shape of the metal matrix composite. The compressed mixture in the die is then heated to sinter the precious metal and ceramic powder. Other techniques for forming the precious metal matrix composite using HIP, and a diamond powder are also disclosed.
