Abstract Details

2013, Master of Science (MS), Ohio University, Mechanical Engineering (Engineering and Technology).
The purpose of this work was to develop a die wear model for superalloy tooling used in multi-channel copper tube extrusion and determine the feasibility of coating superalloys with a chemical vapor deposition (CVD) thin-film for wear improvement. Samples were produced from commercial alloys ATI 720, Inconel 718, and Rene 41 alloys and coated with a multi-layer aluminum oxide CVD coating, Bernex 29 CVD coating offered by Ionbond. Post-coating heat treatment processes for the superalloys were modified to maintain coating adhesion. Pin on disc wear tests were conducted on coated and non-coated samples. The CVD coating provided a decrease in wear rate by at least 70%. Based on the wear test results, a die wear model to predict the service life of extrusion tooling was developed.
