Nickle Base Tungsten Carbide Composite Bar

Panimula ng Ni based welding bar:

Ang bar ng rod welding ay sintered ng CTC at NI-based powder. Ang Ni based welding bar CTC (cast tungsten carbide) ay nasa hindi regular o spherical na hugis na may mas mahusay na paglaban sa pagsusuot at ang nikel na haluang metal ay nasa spherical o halos spherical na hugis at may mahusay na kakayahang umangkop sa cast tungsten carbide. Ang NI based CTC welding bar cladding layer ay may mas mataas na epekto ng pagtutol at mas mahusay na paglaban sa pagsusuot.

Ang SCTC NI na batay sa welding bar wear resistance at resistensya ng kaagnasan ay nasa pagitan ng tubo ng tubo at nababaluktot na lubid. Pangunahin na ginagamit sa bakal na PDC bit, kongkreto na talim ng panghalo, putik na bomba, minero chute, miner drill stem at mekanikal na bahagi ng tunnel rock drill machine atbp. Welded ng oxy-acetylene na may mahina na carburizing flame.
