Erosion-Resistant Coating for Titanium
Abstract
NITRIDES, BORIDES, ADHESION, STRESS CORROSION, PLATING, NICKEL, COMPRESSOR BLADES, IMPELLERS*ABRASION RESISTANT COATINGS, TITANIUM NITRIDES, TITANIUM CARBIDES, TITANIUM ALLOY 6AL 4V, TITANIUM BORIDEThe objective of the program was to develop the application of TIKOTE-C on the Ti-6Al-4V alloy with minimum degradation of mechanical properties. The approach for accomplishing this objective was to protect the titanium microstructure with an intermediate nickel barrier, as well as to provide a ductile layer which might inhibit crack propagation. In addition, embrittling effects due to gas absorption during the coating process were minimized by using a lower process temperature. The program was divided into two major categories: (1) TIKOTE-C coating application development, and (2) extensive mechanical tests. A brief evaluation of the fatigue characteristics and erosion resistance of nickel-plated and titanium diboride-coated titanium test specimens was made.
