Abstract:

A coated cutting insert for use in a chip-forming material removal operation wherein the coated cutting insert includes a substrate that has a flank surface and a rake surface and the flank surface intersects the rake surface to form a cutting edge at the intersection. There is a wear-resistant coating scheme that adheres to at least a portion of the substrate. The wear-resistant coating scheme includes one or more coating layers of one or more of alumina, hafnia and zirconia. There is a wear indicating coating that adheres to at least a portion of the wear-resistant coating scheme. The wear indicating coating includes M(OCN) wherein M is selected from the group comprising one or more of the following titanium, hafnium, zirconium, chromium, titanium-aluminum alloy, hafnium-aluminum alloy, zirconium-aluminum alloy, chromium-aluminum alloy, and their alloys, and x>0, y≧0, z≧0 and y+z>0. A method of making a cutting insert with wear indicating coating including the steps of: providing a substrate with an outer alumina coating layer; applying an as-deposited non-wear indicating coating layer to the alumina coating layer; and treating the non-wear indicating coating layer to convert it to a wear indicating coating layer.

Abstract:

In one aspect, methods of making freestanding metal matrix composite articles and alloy articles are described. A method of making a freestanding composite article described herein comprises disposing over a surface of the temporary substrate a layered assembly comprising a layer of infiltration metal or alloy and a hard particle layer formed of a flexible sheet comprising organic binder and the hard particles. The layered assembly is heated to infiltrate the hard particle layer with metal or alloy providing a metal matrix composite, and the metal matrix composite is separated from the temporary substrate. Further, a method of making a freestanding alloy article described herein comprises disposing over the surface of a temporary substrate a flexible sheet comprising organic binder and powder alloy and heating the sheet to provide a sintered alloy article. The sintered alloy article is then separated from the temporary substrate.
