Friction Material yog ib yam khoom uas siv kev sib txhuam. Sintered hlau txhuam cov khoom yog ib yam khoom tsim los ntawm sintering.

Cov khoom sib txhuam yog cov khoom siv sib txhuam. Sintered hlau txhuam cov khoom yog cov khoom tsim los ntawm sintering. Piv nrog cov khoom siv hlau tsis yog-sintered, nws muaj kev sib txhuam zoo dua, thermal conductivity zoo dua, siab zog, corrosion kuj, thiab lub neej ntev dua. Nws yog cov khoom siv dav tshaj plaws thiab siv dav hauv cov khoom siv sib txhuam niaj hnub. Nws yog dav siv nyob rau hauv industrial machinery, railway tsheb, dav hlau, tsheb thiab lwm yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv lub siab - ceev kis tau tus mob thiab braking teb.

The main manufacturing process of the material is: preparing powder-ingredients-mixing-pressing and forming-sintering. That is the "pressing-sintering" method.

Cov khoom siv tam sim no yog:

1. Raws li cov matrix, feem ntau yog hlau-raws li thiab tooj liab-raws li, ua raws li nickel-raws li thiab tungsten-raws li.

1) Cov matrix muaj pes tsawg leeg ntawm tooj liab-raws li sintered hlau txhuam cov khoom siv yog tooj liab, thiab Sn, Zn, Fe, Ni, P thiab lwm yam khoom siv ntxiv kom ua tiav alloying thaum lub sij hawm sintering. Ntxiv silica, alumina, zirconia thiab lwm yam hlau oxides thiab lwm yam hlau carbides raws li cov khoom sib txhuam; ntxiv graphite, hlau sulfides, fluorides, qis- melting hlau, thiab lwm yam. raws li lubricating Cheebtsam.

2) Cov khoom tseem ceeb ntawm cov hlau -raws li sintered hlau sib txhuam cov khoom yog hlau, thiab cov khoom sib txhuam thiab lubrication tivthaiv zoo ib yam li tooj liab -raws li sintered hlau txhuam cov khoom, nrog zoo thermal stability. Qhov tsis zoo yog tias nws muaj kev sib raug zoo nrog tus khub kev sib txhuam thiab nws yooj yim rau adhesion, kev sib txhuam ntawm qhov sib txawv, kev hnav tsis zoo, suab nrov, thiab lwm yam.
