采用矩形激光均匀强光斑 ,在尖轨易磨损失效部位的表面进行激光相变硬化热处理 ,使尖轨表面硬度提高 ,耐磨性能强 ,增强了材料的疲劳强度 ,并保持了硬化层下部材料的原有特性。严格控制硬化层的深度 ,使其在规定允许范围内 ,保证尖轨的强度指标在技术要求之内 ,尖轨的整体耐磨性能有大幅度的提高 ,成倍的延长了尖轨的使用寿命
Using rectangular laser uniform bright spot, the surface of the sharp rail easy wear and tear failure of the laser phase transformation hardening heat treatment, the sharp rail surface hardness, wear resistance, and enhance the fatigue strength of the material, and to maintain the lower part of the hardened layer of material Original features. Strict control of the hardened layer depth to make it within the specified allowable range, to ensure that the strength of the sharp rail indicators within the technical requirements, the overall wear of the sharp rail has greatly improved, doubling the extension of the useful life of the rail
