中文摘要:
      相比于传统的润滑油、润滑脂,固体润滑剂能够满足极端条件下的润滑要求。向铜基体中掺入固体润滑剂、合适的增强相颗粒,能形成铜基自润滑复合涂层,可以显著提高铜基涂层的减摩耐磨性。在国内外铜基自润滑复合涂层已有研究的基础上,首先综述了铜基自润滑复合涂层的材料体系,即常用固体润滑剂和增强相的适用范围及其作用机理。润滑性能与强度配合协调的问题是铜基自润滑涂层的一个研究关键。然后介绍了制备铜基自润滑复合涂层的传统“热”技术,如粉末冶金、激光熔覆、热喷涂等,但都具有一定的局限性。对比发现,“低温”条件下进行的冷喷涂技术,在制备铜基自润滑涂层方面具有传统涂层制备技术不可替代的优势,可有效克服“热”技术问题,拥有极大的潜在应用价值。要获得厚度大、结合强度高、自润滑性能好且能适应复杂严苛服役环境的涂层,面临着巨大挑战,所以急需研发多润滑相/增强相新型涂层,或尝试冷喷涂复合加工技术。
英文摘要:
      Compared with traditional lubricating oils and greases, solid lubricants can meet the lubrication requirements under extreme conditions. Incorporating a solid lubricant and suitable reinforced phase particles into the copper matrix to form a copper-based self-lubricating composite coating with its friction and wear resistance significantly improved. Based on the review of literatures on copper-based self-lubricating composite coating at home and abroad, the scope of application and mechanism of its composites, i.e. the commonly used solid lubricants and reinforced phase are summed up. The coordination of lubrication performance and strength is a key to the research of copper-based self-lubricating coatings. Then the traditional “thermal” techniques of preparing copper-based self-lubricating composite coatings are introduced, such as powder metallurgy, laser cladding, thermal spraying, etc., which show certain limitation. By comparison, it is found that the cold spraying with “low temperature” conditions has an irreplaceable advantage in the preparation of copper-based self-lubricating coatings. It can effectively overcome the problems of the above “thermal” techniques and has great potential applications. It is a challenge to obtain coatings with large thickness, high bonding strength, good self-lubricating properties and good adaptability to complex and severe serving environments. Therefore, it is urgent to develop new composite coatings with multiple lubricating phases/reinforced phases or an attempt of all kinds of cold spray hyper techniques.
