Powdwr Carbid Twngsten Cast
Mae Powdwr Cast Twngsten Carbide (CTC) wedi'i wneud o doddi a malu W a WC ac mae'n ronynnau llwyd tywyll afreolaidd gyda phwynt toddi uchel (2525 ℃), caledwch uchel (≥ 2000 HV0.1), a gwrthiant gwisgo rhagorol.
Defnyddir CTC i baratoi powdr darnau matrics PDC, powdwr Plasma Arc Welding (PTAW), deunyddiau weldio chwistrellu, electrodau gwrthsefyll traul carbid sment (gwifren), ac ati Y prif bwrpas yw rhag-atgyfnerthu arwynebau sy'n gwrthsefyll traul neu atgyweirio arwynebau sydd wedi treulio. ar gyfer mwyngloddio, olew a nwy, meteleg, peiriannau adeiladu, peiriannau amaethyddol, a diwydiannau dur.
