一、前言 以往要求耐腐蚀的壳体和轴组成的摩擦付,采用1Cr18Ni9Ti材料,在装配调试过程中,轴和壳体的相对运动部位就会产生很深的一条条沟槽,极易咬死,从而造成无法使用。所以要求研制抗咬耐蚀不锈钢。 咬死是一种磨损现象,属于粘着磨损。两金属表面接触时,由面间存在的突起物所引起的高的局部压力使表面薄膜破裂,而洁净的表面一旦接触,作为表面静电平衡的结果,面间便有一个固有的粘着趋势。如果接触面相对运动,所形成的粘着状态便破坏,破断面可以是原有的界面,但往往是在较弱
First, the foreword In the past required corrosion-resistant shell and shaft composed of friction pay, the use of 1Cr18Ni9Ti material, the assembly process, the relative movement of the shaft and the shell will have a deep groove, easily killed , Resulting in unusable. Therefore, the development of anti-bite corrosion resistant stainless steel. Seizure is a wear phenomenon, belonging to adhesive wear. When the two metal surfaces come in contact with each other, the high local pressure caused by the protrusions existing between the surfaces ruptures the surface film. Once the clean surfaces come into contact, there is an inherent tendency to adhere as a result of surface electrostatic equilibrium. If the contact surface relative movement, the formation of the adhesive state will be destroyed, the fracture surface may be the original interface, but often in the weaker
