Title: Surface treatment of metals and alloys
Inventor: BOSTON MALCOLM EDWARD
IPC: C23C8/36
Filed: 1991-03-08
Abstract: The invention provides a method of treating a component made of metal or alloy, in which the component is bombarded with nitrogen ions in a vacuum system at a temperature below that conventionally used for plasma nitriding. The nitrogen ion bombardment is preferably carried out at a temperature below 850 DEG C and for a period of time in the range of 1-2 hours. This method allows surface treatment of a component to be carried out relatively quickly. The invention also provides a method of treating a component made of metal or alloy, in which the surface of the component is cleaned by ion bombardment; the cleaned component is bombarded with nitrogen ions in a vacuum system at a temperature below that conventionally used for plasma nitriding; and a surface coating is then formed on the component. A component is thus produced which has improved properties compared with those obtained hitherto, for example, good adhesion, wear and surface finish properties.
