Description

推土铲表面强化处理方法
技术领域
本发明涉及工程机械领域，具体是一种推土铲表面强化处理方法。
背景技术
推土机是一种工程车辆，前方装有大型的金属推土铲，使用时放下推土铲，向前铲削并推送泥、沙及石块等，推土刀位置和角度可以调整。推土机能单独完成挖土、运土和卸土工作，具有操作灵活、转动方便、所需工作面小、行驶速度快等特点。其主要适用于一至三类土的浅挖短运，如场地清理或平整，开挖深度不大的基坑以及回填，推筑高度不大的路基等。
由于推土机的工作特性，推土铲不仅需要很高的硬度，还需要具有极高的耐磨性能。由于成本原因，以现在的技术无法对推土铲使用的材料做出创造性的改进，为了提高推土铲的硬度和耐磨性能，只能从其表面强化技术着手。
发明内容
本发明为了解决现有问题，提供了一种推土铲表面强化处理方法，大大提高了推土铲的表面硬度和耐磨性，延长了推土铲的使用寿命。
本发明提供了一种推土铲表面强化处理方法，包括以下步骤：
1）在推土铲表面进行渗碳工艺；
2）对推土铲表面进行喷丸处理，所用的喷丸为硬质合金钢球，硬质合金钢球的质量为1kg～2kg，喷速为40～50m/s，喷射时间为连续喷射5min后停止1min，反复至少四次；
3）对推土铲表面进行超音速颗粒轰击，颗粒直径为5-55μm，轰击密度为每平方厘米每秒1000-3000次；
4）采用气相沉积法或双辉等离子法在推土铲表面制备硬化薄膜涂层。
本发明有益效果在于：大大提高了推土铲的表面硬度和耐磨性，延长了推土铲的使用寿命。
具体实施方式
本发明提供了一种推土铲表面强化处理方法，包括以下步骤：
1）在推土铲表面进行渗碳工艺；
2）对推土铲表面进行喷丸处理，所用的喷丸为硬质合金钢球，硬质合金钢球的质量为1kg～2kg，喷速为40～50m/s，喷射时间为连续喷射5min后停止1min，反复至少四次；
3）对推土铲表面进行超音速颗粒轰击，颗粒直径为5-55μm，轰击密度为每平方厘米每秒1000-3000次；
4）采用气相沉积法或双辉等离子法在推土铲表面制备硬化薄膜涂层。
本发明大大提高了推土铲的表面硬度和耐磨性，延长了推土铲的使用寿命。
本发明具体应用途径很多，以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以作出若干改进，这些改进也应视为本发明的保护范围。
