Platinum Aluminide Diffusion

Praxair Surface Technologies offers platinum aluminide coatings, the coating choice for many aviation gas-turbine hot-section airfoils. Compared to the simple aluminides, platinum coatings provide exceptional oxidation protection. They are used for many HP and LP turbine airfoils, where additional environmental protection is needed. Platinum aluminide coatings also provide exceptional Type I and Type II hot-corrosion protection and are used in marine and industrial gas turbines to minimize corrosion.
