Modification Of Titanium

Recent developments of laser surface modification of titanium alloys for increasing their corrosion, wear and oxidation resistance are introduced. The effects of laser processing parameters on the resulting surface properties of titanium alloys are reviewed. The problems to be solved and the prospects in the field of laser modification of Ti alloys are discussed. Due to the intrinsic properties, a laser beam can be focused onto the metallic surface to produce a broad range of treatments depending on the input energy. Thus, composite strengthening coatings can be fabricated by the methods of laser alloying, cladding, pulse laser deposition (PLD), etc., which are promising techniques of producing a layer of new materials on the surface of titanium alloys.

Polarization Technique

Laser surface modification of nine tool steels, namely, plastics mold steels (PMSs), high-speed steels (HSSs) and cold/hot-work steels (CHWSs), was achieved by means of a CW Nd:YAG laser. The microstructure and the phases present in the surface of the specimens were analyzed by optical microscopy, scanning-electron microscopy and X-ray diffractometry. The surface hardness of the specimens was measured using a Vickers microhardness tester. The corrosion characteristics of the laser surface-melted steels in 3.5 wt% NaCl solution at 25 oC were studied by potentiodynamic polarization technique. The microstructures of the surface of the steels were changed completely after laser surface melting. Some steels showed improved corrosion resistance compared with the conventionally hardened specimens due to dissolution of the alloying elements in solid solution. The hardness and corrosion characteristics of all the laser surface-melted specimens are strongly dependent on the amount of passivating elements in solid solution and also on the morphology of the re-precipitated carbides. Both these factors depend on the laser processing parameters and the substrate compositions.

Titanium and titanium alloys are widely used in aeronautical, marine, chemical and biomedical applications and so on, owing to their specific properties such as good corrosion resistance, low densities, high specific strength and modulus, and high-temperature resistance. However titanium and titanium alloys also have many disadvantages, such as low hardness, low wear-resistance and the low corrosion-resistance in some cases, which limit their wider application. Recent years, the corrosion resistance of titanium and titanium alloys is required to elevate in some fields. Proper surface modification can solve the problems effectively. This paper reviews the recent investigations of laser surface modification to improve the corrosion resistant of titanium and its alloys. The microstructures, the corrosion resistance properties, and the influence factors of the coatings were discussed systematically. And the future prospect of the further researches and uses is presented.
