APPLICATIONS:
Hard surfacing ntawm lub taub hau valve, foob rings ntawm siab siab twj tso kua mis thiab qhov chaw ntawm crushers.
DESCRIPTION:
COBALTHARD 1FC npog electrode yog lub siab tshaj plaws hardness standard alloy nyob rau hauv cov pab pawg neeg ntawm cobalt alloys siv rau siab kub abrasive hnav txuam nrog corrosion.Cov deposits ntawm no alloy muaj ib tug loj ntim ntawm chromium carbides uas cuam tshuam zoo heev abrasive hnav kuj.Qhov sib ntxiv ntawm tungsten txhim kho qhov kub thiab txias hardness thiab matrix toughness rau cov nplaum zoo heev thiab cov khoom ua kom yaig hnav tsis kam.Nws sib raug zoo nrog tag nrho cov hlau, nrog rau stainless.
CEEB TOOM RAU SIV:
Preheat ntawm 300ºC thiab ntau dua.Siv PHILARC qhov ntsuas kub qhia cov nplaum lossis PHILARC qhov ntsuas qhov ntsuas kub ntsuas los txiav txim siab seb qhov kub zoo li cas ua ntej vuam.Yog xav paub ntxiv mus saib PHILARC Daim Ntawv Qhia 4 Cov kauj ruam yooj yim rau vuam.
Nws yog qhov zoo rau tom qab cua sov ntawm 600ºC thiab kom txias txias tom qab vuam kom tsis txhob tawg.
Qhuav cov electrodes ntawm 150-200ºC rau 30 - 60 feeb ua ntej siv.Siv PHILARC portable drying qhov cub.
