Abstract
Coated cemented carbide inserts are particularly useful in general turning of superalloys. The inserts are formed from a cemented carbide of WC about 5.0-7.0 wt-% Co, and about 0.22-0.43 wt-% Cr, where the substrate has a coercivity (Hc) of about 19-28 kA/m. The coating contains a single layer of (TiAl)N-layer, where x is 0.25-0.50, with a crystal structure of NaCl type, a total thickness of about 3.0-5.0 μm, (200)-texture, and a compressive residual strain of about 2.5×10-5.0×10, optionally containing an outermost TiN-layer.
