Summary: | A chromium-containing coated cemented tungsten carbide cutting insert (10, 40) that has a substrate (18, 42) and a coating (30, 32, 34, 50). The substrate comprises between about 5.7 and about 6.4 weight percent cobalt, between about 0.2 and about 0.8 weight percent chromium and the balance tungsten and carbon, and a coercive force of about 195 to 245 oersteds.
L'invention porte sur un insert (10, 40) d'outil de coupe de carbure de tungstène cémenté enrobé contenant du chrome comprenant un substrat (18, 42) et un revêtement (30, 32, 34, 50). Le substrat, qui comprend entre environ 5,7 et environ 6,4 % en poids de cobalt, entre environ 0,2 et environ 0,8 % en poids de chrome et le reste de tungstène et de carbone, présente un champs coercitif d'environ 195 à 245 oersteds. |
