A cutting tool includes a substrate on which at least on the functioning parts of the surface thereof a thin, adherent, hard and wear resistant coating is applied, wherein the coating includes a laminated multilayer of alternating PVD or PECVD metal oxide layers, MeX+MeX+MeX+MeX . . . , where at least one of MeX and MeX is a metal oxide+metal oxide nano-composite layer composed of two components, wherein the layers MeX and MeX are different in composition or structure, the laminated multilayer layer has a compositional gradient, with regards to a concentration, in a direction from an outer surface of the coating towards the substrate, the gradient being such that a difference between an average concentration of an outermost portion of the multilayer and an average concentration of an innermost portion of the multilayer is at least about 5 at-% in absolute units.

Coated cutting tool

The present invention relates to cutting tool insert for metal machining on which at least on the functioning parts of the surface thereof a thin, adherent, hard and wear resistant coating is applied. The coating comprises a metal oxide/oxide composite layer consisting of two components with a grain size of from about 1 to about 100 nm. The oxide layer is under a compressive stress.

Coated insert

An element for making an electric contact to a contact member for enabling an electric current to flow between the element and the contact member. The element includes a body having at least a contact surface thereof coated with a contact layer applied against the contact member. The contact layer includes a film including a multielement material with equal or similar composition as any of a layered carbide or nitride that can be described as MAX, where M is a transition metal or a combination of a transition metals, n is 1, 2, 3 or higher, A is an group A element or a combination of a group A element, element and X is Carbon, Nitrogen or both.
