Abstract

本实用新型公开了一种耐磨的激光强化不锈钢立柱，属于煤矿井下支护设备。它是在不锈钢立柱体表面加工有激光强化层。本实用新型将激光强化技术用于立柱表面处理延长了不锈钢立柱的寿命。

Description

激光强化不锈钢立柱
技术领域
本实用新型涉及煤矿井下支护设备，尤其涉及液压支架的不锈钢立柱。
背景技术
目前普通煤矿井下液压支架的立柱是通过表面镀烙方法，来实现表面防生锈、防腐蚀，因为镀烙层耐磨性差，其寿命为1—1.5年，并且镀烙层会出现起皮、脱皮的现象，从而乳化液就会腐蚀立柱表面，影响液压支架的使用效果。因此，很需要一种新的防腐层的立柱。激光强化体技术是目前用于钢铁表面处理的新技术，还没有用于立柱表面处理的。
发明内容
本实用新型为解决立柱表面的耐磨问题，提供一种新的耐磨层的不锈钢立柱。
本实用新型是在不锈钢立柱体表面加工有激光强化层。
通过激光强化处理后的立柱，其基体表面硬度达到HV410。激光强化技术在立柱表面工程技术上的应用，是利用激光束能量高度集中、方向高度集中的特性，在廉价金属材料表面形成一层硬度高、无裂纹，且与基体呈冶金结合的高性能涂层，将立柱金属良好的坚韧性和涂层材料的高硬度、高化学稳定性、高耐磨性结合起来，达到防锈、防腐蚀和耐磨的目的。本实用新型激光强化不锈钢立柱使用寿命达镀铬立柱的5-6倍。
附图说明
图1是本实用新型的主视剖面图。
图中：1—立柱体，2—激光强化层。
具体实施方式
实施时，将立柱体1置于激光强化表面处理机上，使立柱移动和旋转，从而在立柱基体上形成一层激光强化层2。
