枪炮身管的烧蚀寿命至今仍然是一个极为重要的问题,近几十年来人们为提高身管寿命进行了广泛的研究,取得了很大的进展。就目前的情况来看镀铬、缓蚀添加剂、炮管自紧等已大量用于生产,其它一些途径如身管内膛氮化,各种表面涂层,新的弹带材料、耐热合金衬管等也进行了研究。在此,仅就身管内膛氮化的研究情况、我们的试验结果及氮化防烧蚀的前景作一简单介绍。 The ablation life of the barrel is still an extremely important issue to date. In recent decades, people have made extensive research to improve their life expectancy and made great progress. In the current situation, chrome, corrosion inhibitors, self-tightening and other barrel have been used in large quantities for production, and other methods such as barrel nitriding, a variety of surface coatings, new lanyard material, heat-resistant alloy liner Also studied. Here, only the case of the research into the bore tube, our test results and prospects for nitrification and ablation make a brief introduction.
