Analysis of Distribution of Temperature and Stresses During the Friction Metallisation of AlN Ceramics with Titanium

The article presents the results of the numerical analysis of an AlN-Ti joint obtained during friction welding, where a titanium probe was rubbed frontally into the base of nitride ceramics. The process aimed to create a thin metallic (titanium) coating on the ceramic base enabling its further joining with metals. Until today, the metallisation of ceramics through friction has not been used for the metallisation of ceramics and, as initial tests have proven, this solution can constitute an advantageous alternative to currently used expensive processes of ceramics metallisation. The numerical modelling of the friction of AlN ceramics with titanium enabled the obtainment of information concerning the distribution of temperature fields and stresses on the contact surfaces of the AlN-Ti system during friction. The obtained results will be useful when analysing the mechanism related to the formation of the interpass of the joint connecting the AlN ceramics with z titanium.
