Latest Patents

Nieh's latest patents include innovative techniques for surface preparation and deposition of titanium nitride. One patent describes a method that replaces conventional Ar.sup.+ ion bombardment with hydrogen-ion bombardment. This new process effectively cleans the substrate surface through chemical reactions, minimizing sputtering and removing graphite from cast iron surfaces. The removal of graphite is crucial as it significantly improves the wear resistance of titanium nitride coatings. The deposition process involves reactive sputtering with high-flux Ar.sup.+ ions, resulting in superior wear properties and adhesion compared to traditional methods.

Another patent focuses on plasma-enhanced magnetron-sputtered deposition (PMD) of materials. This technique allows for low-temperature deposition of hard, wear-resistant thin films onto large, irregularly shaped objects without the need for substrate manipulation. The PMD process utilizes metal sputter targets immersed in a plasma generated from a combination of inert and nitrogen or carbon gases. This innovative approach enables independent electrical control of the substrate, metal targets, and plasma, enhancing the properties of the deposited films.
