Abstract: The present invention relates to coated cemented carbide inserts, particularly useful in general turning of superalloys. The inserts are characterized by a composition of the cemented carbide of WC, 5.0-7.0 wt-% Co, 0.22-0.43 wt-% Cr and a coercivity (Hc) of 19-28 kA/m. The coating consists of a single (Ti x Al 1-x )N-layer, where x is between 0.25 and 0.50, with crystal structure of NaCl type, total thickness of between 3.0 and 5.0 µm, (200)-texture, and compressive residual strain of between 2.5*10 -3 and 5.0*10 -3 , possibly followed by an outermost TiN-layer.

Abstract: A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics, cubic boron nitride based material or high speed steel, onto which a hard and wear resistant coating is deposited by physical vapor deposition. The coating includes a polycrystalline nanolaminated structure of alternating layers A and B where layer A is (Ti,Al,Me1)N and Me1 is optionally one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table, layer B is (Ti,Si,Me2)N and Me2 is optionally one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table including Al with a thickness between 0.5 and 20 μm and method of making the same. This insert is particularly useful in metal cutting applications generating high temperatures with improved edge integrity, machining of super alloys, stainless and hardened steels.
