Abstract

In the field of microabrasion-corrosion, there has been limited research progress in modelling the process due to the complex interplay between the two processes involved. One of the crucial developments in the field has been the microabrasion-corrosion maps based on experimental results. However, mathematical modelling to develop the maps has not been attempted before. This work aimed to construct mathematical models for predicting the microabrasion-corrosion rate for mild steel and pure titanium in aqueous slurry conditions. The methodology developed was used for the construction of microabrasion-corrosion maps. The maps were constructed in two forms: (1) regime maps that identify the underlying mechanisms of microabrasion-corrosion and (2) wastage maps that identify the magnitude of the wastage rate. The effects of abrasive particle size and solution pH were shown on the maps. These maps have not been reported before and can form a basis for material selection and process optimisation for various microabrasion-corrosion applications, such as hip joint conditions. The advantages and applications of these maps are addressed in this paper.
