钛合金表链dlc涂层掉了

钛合金表(biao)链的(de)DLC涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)掉了可(ke)(ke)能有以下原因：1.涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)质(zhi)量问(wen)题：DLC涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)是(shi)一种(zhong)钻石类涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)，如(ru)果(guo)涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)质(zhi)量不好(hao)或(huo)者(zhe)涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)厚度(du)不够，容易出(chu)现掉落的(de)情况。2.使用(yong)(yong)不当：如(ru)果(guo)佩戴(dai)的(de)时(shi)候(hou)不小心(xin)碰到硬物，或(huo)者(zhe)在运动、工作(zuo)时(shi)遭(zao)受(shou)撞(zhuang)击，也可(ke)(ke)能导致DLC涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)的(de)掉落。3.长时(shi)间使用(yong)(yong)：如(ru)果(guo)表(biao)链长时(shi)间使用(yong)(yong)，经过磨损和暴露在各种(zhong)环境中，DLC涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)可(ke)(ke)能会(hui)自然掉落。以上只是(shi)可(ke)(ke)能性原因，具(ju)体(ti)(ti)原因还(hai)需要根据(ju)具(ju)体(ti)(ti)情况进(jin)(jin)行(xing)分析。如(ru)果(guo)您的(de)钛合金表(biao)链的(de)DLC涂(tu)(tu)(tu)(tu)层(ceng)(ceng)(ceng)掉了，可(ke)(ke)以尝试到专业(ye)的(de)手表(biao)维(wei)修店(dian)进(jin)(jin)行(xing)修复。

经过多年的(de)(de)研(yan)究(jiu)(jiu)表明：由于(yu)类金(jin)刚石涂(tu)(tu)(tu)层(ceng)的(de)(de)内应力高、热稳定(ding)性差(cha)及与黑(hei)(hei)色(se)(se)金(jin)属间的(de)(de)触媒(mei)效应使(shi)SP3结(jie)构向(xiang)SP2转变等缺(que)点，决定(ding)了它目前只能应用(yong)(yong)于(yu)加工(gong)有(you)色(se)(se)金(jin)属，因而(er)限制了它在(zai)机加工(gong)方面的(de)(de)进(jin)一步(bu)应用(yong)(yong)。但是近(jin)年来(lai)的(de)(de)研(yan)究(jiu)(jiu)表明，以SP2结(jie)构为主的(de)(de)类金(jin)刚石涂(tu)(tu)(tu)层(ceng)(也(ye)称为类石墨涂(tu)(tu)(tu)层(ceng))硬度也(ye)可(ke)达(da)到(dao)20～40GPa，却不存在(zai)与黑(hei)(hei)色(se)(se)金(jin)属起触媒(mei)效应的(de)(de)问题，其摩擦系数很(hen)低又有(you)很(hen)好(hao)的(de)(de)抗湿性，切(qie)(qie)削(xue)时(shi)可(ke)以用(yong)(yong)冷却剂(ji)也(ye)可(ke)用(yong)(yong)于(yu)干切(qie)(qie)削(xue)，其寿命比(bi)无涂(tu)(tu)(tu)层(ceng)刀有(you)成倍(bei)的(de)(de)提(ti)高，可(ke)以加工(gong)钢铁材(cai)料，因而(er)引(yin)起了涂(tu)(tu)(tu)层(ceng)公司、刀具厂家(jia)的(de)(de)极大(da)兴趣。假以时(shi)日，这种新型的(de)(de)类金(jin)刚石涂(tu)(tu)(tu)层(ceng)将会在(zai)切(qie)(qie)削(xue)领域得到(dao)广(guang)泛的(de)(de)应用(yong)(yong)。传统硬质薄(bo)膜(mo)(mo)的(de)(de)摩擦系数都在(zai)0.4以上，这使(shi)得DLC涂(tu)(tu)(tu)层(ceng)在(zai)许多摩擦学领域具有(you)替(ti)代传统硬膜(mo)(mo)的(de)(de)潜力。
