| 摘 要： | 测定了CD—4MCu合金在69％H_3PO_4,69％H_3PO_4+500ppm NaCl介质中的腐蚀率、腐蚀磨损—载荷关系及摩擦系数,还用SEM观察了磨痕,实验表明它的耐腐蚀磨损性能优于一般的304不锈钢和高耐蚀的Carpenter20Cb3合金,从CD—4MCu合金双相组织特点可知其中低Ni的面心立方γ相有较高的抗磨损能力。

| Abstract: | The corrosion rate, together with corrosive wear and corrosion coefficient under load, of CD--4MCu alloy in 69% H_3PO_4 or 69% H_3PO_4+500 ppm NaCl solution was measured,and the morphology of their wear tracks was then observed by SEM. The CD--4MCu alloy isrevealed to be superior in corrosive wear resistance to 304 stainless steel and even to Carpenter 20Cb_3, a high corrosion resisting alloy. From its features of duplex phase structure, it could be suggested that the weight loss related to mechanical factor was improved by existence of austenitic phase due to its deformation strengthening. |
