失效的鹽亭機械密封，摩擦副端麵常會留下很細的徑向裂紋，或者是徑向裂紋兼有水泡痕，甚至龜裂。這是由於密封過熱引起的，特別是陶瓷、硬質合金密封麵容易產生這類損傷。介質潤滑性差、過載、操作溫度高、線速度高、配對材料組合不當等，其中任何一種因素，或者是幾種因素的疊加，都可以產生過大的摩擦熱，若摩擦熱不能及時散發，就會產生染整鹽亭機械密封reliewen，congerchuxianguodumosunhegaoxielou。jiejuemifengguorewenti，chugaibianduanmianmianjiwai，jianshaozaihewai，haikecaiyongjingzhixingmifengbingjiadaoliutaoqiangzhilengquexunhuanliutidaoxiangmifengmian，huozaimifengduanmianshangkailiutidonglicaolaijiayijiejue。mocaduanmianshangyouxuduoxixiaoderebandianhegulidebiansequ，zheshuomingmifengjianzaigaoyahereyingxiangxiabianxingniuqu。duiyuduanmiandederebianxing，yibandejisuanfangfashibuyunxude，yingcaiyongyouxianyuanfajisuan，yibiangaijinmifenghuandesheji。
表麵噴塗硬質材料的密封環，無論是噴塗船用鹽亭機械密封陶瓷還是硬質合金，在熱負荷下去麵層都有可能在基材上其鱗片或剝落。出現這種現象，說明密封出現過幹摩擦。
