Oxidation is the process when oxygen combines with an element, changing the appearance of the element. When iron reacts with oxygen and changes to rust, this is an example of oxidation. ... any process in which oxygen combines with an element or substance, either slowly, as in the rusting of iron, or rapidly, as in the burning of wood the process of increasing the positive valence or of decreasing the negative valence of an element or ion

The present invention discloses a Pt Ni Al bonding layer doped with binary trace active elements and capable of being completely oxidation resisting at 1200 DEG C and a preparation method thereof and belongs to the field of novel thermal barrier coatings and the preparation technologies. According to the invention, firstly, a Pt layer with the thickness of 5-10 microns is prepared on a nickel base monocrystal high temperature alloy matrix through the plating or the electron beam physical vapor deposition method, and then a NiAlHfZr coating with the thickness of 20-60 microns is deposited on the Pt layer through the electron beam physical vapor deposition method. The Pt layer reduces the interfacial holes and effectively improves the adhesion of an oxidation film; binary doping of Hf, Zr enables the NiAl coating surface to be smoother and denser and enables the oxidation film generated during the oxidation process on the coating surface to be straighter, especially with little oxidation increase, and greatly improves the oxidation resistance of the coating. The Pt Ni Al bonding layer is completely oxidation resisting at 1200 DEG C. The service life of the coating is prolonged to certain degree through doping of binary elements namely Hf and Zr and Pt modification.
