Provided is a multilayer hard film capable of elongating a lifetime of a member. A multilayer hard film () is formed by alternately stacking a layer A () made of TiSi(BCN) [where 0.05&#x2266;x&#x2266;0.4, p&#x2267;0, q&#x2267;0, r&#x3e;0, p+q+r=1], and a layer B () made of at least one selected from the group of TiBCN[where 0.05&#x2266;a&#x2266;0.5, 0.25&#x2266;b&#x2266;0.6, 0&#x2266;g&#x2266;0.5], SiCN[where 0.2&#x2266;c&#x2266;0.5, 0.25&#x2266;d&#x2266;0.5], BCN[where 0.03&#x2266;e&#x2266;0.25, 0.3&#x2266;f&#x2266;0.55], TiB, SiC and BC, one another over the surface of the substrate ().

Multilayer hard film and method for producing same

A coated metal substrate has at least one layer of titanium based hard material alloyed with at least one alloying element selected from the list of chromium, vanadium and silicon. The total quantity of alloying elements is between 1% and 50% of the metal content, the layer having a general formula of: (TiCrVSi)CNO.

Coated cutting tool, cutting member or wear part

Disclosed is a crystalline hard coating layer having no cracks, which exhibits both high hardness and excellent wear resistance at the same time. A method for forming the hard coating layer is also disclosed. A crystalline hard coating layer () coating a substrate () is formed by a PVD method, and contains Si and C as essential components, while containing an element M (which is one or more elements selected from among groupA elements, groupA elements, groupA elements, groupA elements, B, Al and Ru) and N as optional components. The crystalline hard coating layer () has the following composition: SiCNM(where 0.4&#x2266;x&#x2266;0.6, 0&#x2266;y&#x2266;0.1, and 0&#x2266;z&#x2266;0.2).
