钴基合金有极好的耐热、耐腐蚀和抗高温氧化性。钴基合金粉是在Co-Cr-W（Mo）合金基础上添加适量的B. Si元素而创制的。B. Si元素的加入使Co-Cr-W(Mo)合金具有了自熔性合金的特点，合金熔点明显降低，脱氧造渣性能好。适度加入部分Ni，在600-800℃温度范围内可耐高温,抗氧化,硬性更好.耐磨、耐腐蚀性能良好。抗含硫燃气腐蚀。

 Cobalt base alloy has exceent heat resistance. Corrosion resistance and oxidation resistance. Cobalt-based alloy powders is in Co-Cr-W (Mo) based on tae alloy add right amount B. Si elements and initiative. B.Si elements  join to make  Co-Cr-W (Mo) alloy has the characteristics of the self fluxed alloy. The significantly lower melting point alloy. Deoxidizing slay ma king good performance. Moderate to join part Ni. In the temperature range 600-800℃ high temperature resistant. The oxidation resistance. Red hardness wear-resisting corrosion resistance. Sour gas corrosion resistance is better.
