WD-M3 Sebaka se boreleli
Boreleli bo Boreleli
Letlapa le Koaheletsoeng la Chromium Carbide
MOLEMO:
* Sebaka se boreleli, se koaheloa ke pase e le 'ngoe, Ha ho lifaha tse chesellang holim'a metsi
* Sebopeho se sa fetoheng sa microstructure le ho thatafala ho fihlela moleng oa fusion
* Tšebelisano e tlase ea likhohlano
* Abrasion e ntle haholo le thepa e hanyetsanang le tšusumetso
* Mocheso o sebetsang <600℃
* Ka boikhethelo ka sekoaelo se ikhethileng se seng sa makenete
* E fumaneha ka leloala le ka holim'a metsi pele ho belisoa
