钎焊金刚石工具用铜锌钛钎料
摘要：
一种钎焊金刚石工具用铜锌钛钎料，其特征在于：所述铜锌钛CuZnTi钎料包括下述重量比的原料，其中：铜45.0~70.0%、锌28.0~47.0%、钛0.1~15.0%；所述铜锌钛CuZnTi钎料还包括下述重量比的原料中的任意一种或两种以上组合，其中：锰0~15.0%、镍0~15.0%、硅0~2.0%、铬0~5.0%、镧0~0.5%或铈0~0.5%。本发明的优点在于：可以使金刚石与基体形成牢固冶金结合，结合强度高；钎料熔点较低，对金刚石热损伤小，易于钎焊；钎料塑性好，可加工成片、粉等形状；不含银等贵重金属元素，可在气体保护下钎焊金刚石制品，工艺简单，成本低。
摘要（英）：

The invention discloses a CuZnTi solder for a soldering diamond tool, which is characterized by comprising the following raw materials by weight ratio: 45.0-70.0% of copper, 28.0-47.0% of zinc and 0.1-15.0% of titanium; and the CuZnTi solder also comprises any one or the combination of more than two of the following raw materials by weight ratio: 0-15.0% of manganese, 0-15.0% of nickel, 0-2.0% of silicon, 0-5.0% of chromium, 0-0.5% of lanthanum or 0-0.5% of cerium. The CuZnTi solder has the advantages that firm metallurgical bonding of diamonds and matrixes can be formed with high bonding strength, and the solder has low melting point, little temperature damage on diamonds and good plasticity, is easy to be soldered, can be processed into shapes of sheets, powder and the like, does not contain silver and other noble metal elements, and can solder diamond products under gas shield with simple process and low cost.
