在工业领域,约占世界1/3的一次性能源被摩擦过程消耗;由于磨损造成60%机械装备失效,因摩擦损失可以占到GDP总量的5%~7%;摩擦降低18%,燃油消耗可节约900亿美元,CO2排放减少2.9亿吨。 传统减摩抗磨手段.润滑油脂添加剂:摩擦改进剂、油性剂、极压抗磨剂、清净分散剂等.二烷基二硫代磷酸锌(ZDDP)和二烷基二硫代氨基甲酸钼(MoDTC),生物毒性;硫酸盐灰分、磷、硫污染环境.固体润滑剂:二硫化钼、石墨、PTFE等.机械设备面临日益严苛的服役工况环境:宽温域、极限高/低速、极限重/轻载、腐蚀、高真空、强辐射等 新型减摩抗磨手段.表面织构技术.纳米材料添加剂.先进的涂层.新型耐磨材料.表面膜技术.新型润滑介质 含有的P,S等元素会对尾气催化剂(三元催化剂)产生毒害作用:产生严重犁沟现象。在5.55 MPa产生200 ℃ ZDDP 混合油。 ZDDP作为极压抗磨剂的代表,其劣势表现: 1. ZDDP中的磷会使催化转化器中的贵金属催化剂中毒。 2. 在一些恶劣条件下(接触应力超过70MPa,温度超过200℃的)都面临着抗磨性能不足的困境。 传统的添加剂在抗磨性能也面临着严重的挑战。 3. 由于环境污染等原因,磷化物和硫化物是被严格限制使用,逐步被替代是大势所趋。 全合成纳米陶瓷自修复剂 经过近20年的科技攻关,突破国外技术壁垒,解决我国高端装备发展中摩擦磨损问题而研发产品。 技术指标 参数 粒径 小于30nm 腐蚀性 无 挥发性 无 成膜能力 强 成膜强度 类金刚石(DLC 硫、磷、氮或锌% 无   本发明专利源自为解决航天和军工领域国外技术壁垒而开发,解决工业领域的摩擦、磨损领域问题而开发的颠覆性技术产品,是解决国外“卡脖子”的关键技术。 研发团队负责人在清华大学摩擦学国家重点实验室博士期间、清华大学汽车系博士后期间,北京交通大学任教期间,经过20多年的不断研发突破,已可实现全人工合成制备纳米级别智能在线自修复剂产品。 产品由全人工合成工艺制备,性能稳定,性价比高。生产环节及应用环节可全过程实现“0”排放,符合国家“3060”双碳战略目标鼓励的高端装备领域发展的新材料技术。 应用案例 一、在轨卫星轴承测试  某所在轨卫星在轨期间轴承不能维修,所处环境恶劣,为增加其可靠性,采用本产品。 高低温:火星表面温度-63℃,月面最高温度123 ℃; 高真空:10-3Pa以上; 大载荷:接触应力超过1GPa; 达到的关键指标: 在内外圈滚道形成厚度大于2µm的自修复膜,修复膜表面干摩擦系数小于0.1;相同工况条件下,纳米硅酸盐自修复剂的使用将轴承寿命提高50%,可靠性提高30%。...
