Determining wear by erosion in coated materials

Abstract:

In this paper the erosion rate of ceramic coating using a software application which includes parameters related to the erosive wear process is determined. The application was done using SharpDevelop 4.2, a free and open integrated development environment in C# language. Moreover, the program makes use of the open source libraries MySql to manage the data containing the erosion parameters and ZedGraph to plot the data. Erosion of layers of titanium nitride (TiN) and chromium nitride (CrN) deposited on AISI 4140 steel substrates was experimentally studied and results compared with the software results. Results show that the erosion rate reaches its maximum value when the angle of incidence is 90° and that experimental and calculated values of erosion rate are well correlated.
