12crni3（12铬镍3）圆钢//12crni3（12铬镍3）圆钢价格
１２ＣｒＮｉ３Ａ珠光体型渗碳钢在淬火后低温回火 或高温回火都有良好的综合力学性能。其低温韧性好，缺口敏感性小，切削加工性能良好，冷变形塑性 中等， 但有回火脆性和形成白点的倾向［１］ ，已用于制造飞机发动机各类齿轮、轴、活塞涨圈、滚子等。采用１２ＣｒＮｉ３Ａ制造的航空发动机中传动齿和轴， 在工作中既受到强烈的摩擦，又受到很大的交变应力和冲击载荷作用，易发生疲劳和磨损。为了提高其耐磨性能，一般采用渗碳处理，使得表层获得高的表面硬度、耐磨性及高的接触疲劳强度，延长零件的使用寿命。但是，渗碳处理温度较高，在处理后工件的变形大， 渗碳层硬度和耐磨性提高有限。研究表明，采用机械研磨法、超声喷丸等方法使得材料表面晶粒细化，晶界增多，这些表面区域高体积分数的晶界为原子扩散提供了理想的通道，有助于大幅度地提高材料表面化学元素的渗入浓度和深度，降低化学处理温度和减少保温时间， 有利于对精密零件实施有效的化学处理［２］ ，但是受加工设备和工件型面尺 寸等条件制约，难以实现广泛的工业应用。近年来发展的一种新型的表面强化技术— ——激光冲击强化技术（ＬＳＰ） ，是通过激光诱导等离子体冲击波在材料表面引起塑性变形，残留较大的压应力［３］ ，同时使 得表层形成高密度位错，晶粒细化，甚至达到纳米 级［ ４－７］，显著提高材料的抗疲劳［８－１５］、耐磨损［１６］ 和抗应力腐蚀［１７－２０ ］等性能。 12CrNi3A pearlitic infiltration of carbon steel in the quenched tempered at low temperature or high temperature tempering has good comprehensive mechanical properties. Good low-temperature toughness, small notch sensitivity, good cutting properties, cold deformation plasticity medium, but temper brittleness and the formation of white spots tend to [1], has been used for manufacturing aircraft engine of all kinds of gear, shaft, piston ring, roller etc.. The 12CrNi3A manufacturing of the aviation engine in the transmission of teeth and shaft, in the work of both strong friction, but also by a large alternating stress and impact load, prone to fatigue and wear. In order to improve its wear resistance, the surface hardness, wear resistance and high contact fatigue strength of the surface are obtained by carburizing process, and the service life of the parts is prolonged. However, the carburizing process temperature is higher, the deformation of the workpiece is large, and the hardness and wear resistance of the coating is limited. The research shows that the grain size and grain boundary of the material surface can be improved by mechanical polishing method and ultrasonic peening method, which can improve the concentration and depth of chemical elements, reduce the temperature and reduce the heat preservation time. It is beneficial to implement effective chemical treatment for precision parts. However, it is difficult to realize a wide range of industrial applications. In recent years, a new type of surface strengthening technology, laser shock processing (LSP), is a new type of laser induced plasma shock wave in the material surface. The residual stress of the material is high density dislocation, grain size, and even reach the nano scale (15 7), and the anti fatigue of the material is significantly improved.
