Self-lubricating Ceramic ncej thiab ncej foob

Lus piav qhia luv luv:

Self-lubricating Ceramic Ncej / Ncej foobtau txhim kho cov khoom siv ntawm lub hauv paus ntawm kev tswj hwm lub zog qub, kua qaub thiab alkali tsis kam, thiab kev sib txhuam tsis kam ntawm cov khoom alumina.Qhov loj tshaj feature yog txo qhov coefficient ntawm kev sib txhuam.Cov shafts thiab ncej ntsaws ruaj ruaj siv cov khoom siv no qhia pom tseeb qhov zoo.Piv txwv li: lub neej ntev, qis suab nrov, kev ruaj ntseg zoo dua, thiab kev tiv thaiv zoo ntawm lub cev muaj zog.

Cov khoom siv micro-textured self-lubricating ceramic txhim kho cov khoom siv kho tshuab ntawm Al2O3 ceramic khoom.Cov pob txha toughness thiab flexural lub zog ntawm cov xim av nws tus kheej-lubricating ceramic ncej yog 7.43MPa·m1/2 thiab 504.8MPa, raws li, uas yog hais txog 0.4% thiab 12.3% siab dua cov zoo tib yam alumina ceramic ncej, qhov siab tshaj plaws kev sib txhuam coefficient yog txo los ntawm kwv yees li 33.3% thiab qhov tsawg kawg nkaus kev sib txhuam coefficient yog txo los ntawm 18.2%.
