Abrasive article having a diamond-like coating layer and method for making same

A method for making an abrasive article, comprising the steps of:

• (a) providing a substrate having at least one major surface;
• (b) forming an abrasive coating on said major surface, wherein said abrasive coating comprises a plurality of abrasive particles and an organic binder medium;
• (c) applying sufficient current to a carbonaceous cathode to form a plasma of carbon constituents forming said cathode;
• (d) permitting said plasma to be directed in a path through an anode:
• (e) maintaining said abrasive coating within said path at a temperature sufficiently low effective to prevent substantial degradation of said organic binder medium to form a diamond-like carbon film on said abrasive coating, said diamond-like carbon film having an average thickness of at least about 100 Angstroms and a plasmon energy of 26 eV or more.
