The wider use of many structural materials in the automotive, aerospace and energy sectors is limited by their marginal environmental resistance, whether it is resistance to high temperature oxidation or wears resistance. The use of coatings is an effective way to improve their environmental resistance.

In the development of novel coatings thermodynamic modeling is a powerful tool for designing materials and predicting properties, microstructure and behavior in working conditions, thus reducing the amount of experimentation necessary.

This work reports on the development of novel coatings for oxidation and wear protection an the optimization of the coating disposition process using thermodynamic modeling. BAL and Al-Mn coatings were deposited on ferritic martensitic steels by pack cementation and CVD-fluidized bed in order to increase their oxidation resistance for use in the nergy sector in boilers or supercritical steam turbines.

The surface of Ti-alloys was modified with single element boride coatings and multielement Mo-Al coatings using pack- cementation and by a chemical halogenations treatment in order ti improves high temperature oxidation and wear properties. Process parameters were optimized by thermodynamic calculations usingThermo-Calc software and some important thermodynamic aspects of the processes are established.
