身管烧蚀及缓蚀剂作用机理研究现状

Research Status of Gun Barrel Erosion and Inhibitor Mitigation Mechanism

身管烧蚀磨损严重限制了火炮性能的提高和服役年限的延长。为延长身管寿命、发展高威力火炮,需增强火炮身管的抗烧蚀磨损能力。从热冲击、化学侵蚀、机械磨损三方面综述国内外身管烧蚀机理的研究现状,分析认为烧蚀磨损的发生与加剧主要归结于热-化学-机械复合作用。在此基础上梳理缓蚀剂技术抑制身管烧蚀磨损的机理,指出纳米材料在缓蚀剂研制中的意义,无机氧化物和含氮有机材料在发射环境下可对身管内壁形成保护。对缓蚀剂的设计作出展望,为新型缓蚀剂设计提供有益思考。

Serious wear and erosion of barrel has limited the improvement of artillery performance and the extension of service life. In order to extend the life of barrel and increase gun performance,it is necessary to enhance anti-erosion endurance and resistance to attrition of artillery barrel. It summarized the domestic and international research status of wear and erosion mechanism of barrel in terms of thermal damage,chemical corrosion and mechanical wear. It was analyzed that the occurrence and aggravation of wear and erosion was primarily attributed to thermal-chemical-mechanical effects. Based on this,an analysis is made of the mitigation mechanism of the erosion inhibiting agent. The significance of nanometer materials in producing inhibitor is pointed out. And it is also pointed out that inorganic oxide and nitrogenous organic materials could protect gun bore under firing condition. Moreover,prospects in the future are envisioned in the design of inhibitor and provided thought-provoking ideas for the design of new type of inhibitor.
