熱處理加工廠家講解等離子滲氮活塞環的優勢

來源www.agroison.com 2018-12-17

活塞環經過等離子滲氮提高了環的表面硬度(≥ 700HV0.1),摩擦力矩小,摩擦因數小,減摩性好,耐磨性高,延長了活塞環的使用壽命。

活塞環經過等離子滲氮改變了環和汽缸套這對摩擦付的表面晶體結構,提高了活塞環的抗咬合性及抗拉缸能力。

等離子滲氮活塞環

活塞環經過等離子滲氮表面粗糙度比原來略有降低,有利于環與缸的初期磨合。滲氮時基體的石墨不能被滲氮層覆蓋,石墨還保持它原有的儲油和潤滑性能。而且,滲氮試樣磨合接觸面的溫度比未經滲氮處理試樣低,有利于環在缸套中高速運動時建立潤滑油膜。

等離子滲氮與其它滲氮方法比較,滲氮速度快,省電,耗氣量少,對環境無污染,質量穩定,滲氮時發生的成本低。
