Lijevani volfram karbid u prahu<\/h1>\n

Prah od lijevanog volfram karbida (CTC)<\/strong> napravljen je od taljenja i drobljenja W i WC i nepravilne su tamnosive \u010destice s visokim tali\u0161tem (2525 \u2103), visokom tvrdo\u0107om (\u2265 2000 HV0.1) i izvrsnom otporno\u0161\u0107u na tro\u0161enje.<\/p>\n

CTC se koristi za pripremu PDC matri\u010dnih bitova u prahu, praha za zavarivanje plazma lukom (PTAW), materijala za zavarivanje raspr\u0161ivanjem, elektroda otpornih na habanje od cementnog karbida (\u017eica), itd. Primarna svrha je prethodno oja\u010dati povr\u0161ine otporne na habanje ili popraviti istro\u0161ene povr\u0161ine za rudarstvo, naftu i plin, metalurgiju, gra\u0111evinske strojeve, poljoprivredne strojeve i industriju \u010delika.<\/p>\n
