　　钴基合金是在钴铬合金中熔入适量的钨和碳，钨的加入使钴基体进一步固溶强化。碳在钴中的溶解度很小，因而加入的碳和过量的钨形成 WC，W₂C，M₆C等碳化物，这些硬质相弥散分布在钴基体中，产生析出强化作用，使该类合金在800℃高温下，仍能保持优异的高温强度和高温硬度，因此钴、铬、钨、碳合金具有优异耐高温磨损、抗高温氧化和热疲劳等综合性能。
　　Cobalt-base alloy is produced by melting suitable amount of tungsten and carbon into the cobalt-chrome alloy, which will enhance the solid-solution strengthening of the cobalt base. For the low solubility of carbon in cobalt, the added carbon and superfluous tungsten may generate WC，W₂C，M₆C and other carbides. The hard materials distribute in the cobalt base and strengthen the separation process, thus the alloy can maintain excellent intension and rigidity under high temperature of 800℃. Thus, the cobalt, chrome, tungsten and carbon alloy have integrated performance of preventing the high temperature wear, oxidation and thermal fatigue.
　　钴在417℃温度以下，为密排六方结构，具有低的摩擦系数，而具有很好的耐磨性。在417℃温度时发生由密排六方晶体，向面心立方晶体的转变，而产生体积应力。因此在喷焊时一般均需将被焊工件预热到500℃～600℃，以防钴基焊层开裂。
　　Below 417℃,cobalt is in dense-hexagonal structure,it has lower frictional coefficient and sound wear resistance. The structure of cobalt will change from dense-hexagonal crystal into face-center-cubic structure under 417℃. The volume stress may appear. Therefore, the welding pieces should be warmed up to 500℃～600℃ to avoid the crack for cobalt-base welding layers.
