Study of the Heat Treatment and Surface Coatings Influence on the Erosion Behavior of Aluminum and Steel Alloy

The current study is observing the erosion behavior as a surface process that depends on the type and size of eroding particles mixed with water, their pressure intensity, angle of impact, and the surface properties of the eroded material. Aluminum and steel alloys are classic materials used extensively in industry that are suffering erosion as they are parts of equipment working in harsh environmental conditions. The present research involves performing erosion testing on 6061 Aluminum, 4140 Steel, and other metals in their original state, after the corresponding heat treatment and after coating their surface with titanium nitride. The substrates are coated with micron size thickness titanium nitride using the DC high vacuum magnetron sputtering deposition system. The coatings’ thickness is in-situ monitored using a quartz crystal microbalance and ex-situ evaluated using a profilometer. The chemical composition of the structures is characterized using the X-Ray diffraction analysis. All samples are evaluated by a custom designed erosion apparatus using different impingement intensities of eroding particles and angles of impact.
