Titanium and its alloys possess several attractive properties that include a high strength-to-weight ratio, biocompatibility, and good corrosion resistance. However, due to their poor wear resistance, titanium components need to undergo surface hardening treatments before being used in applications involving high contact stresses. Laser nitriding is a thermochemical method of enhancing the. 1. Nitriding: The use of chemical heat treatment techniques such as plasma nitriding, multi-arc ion plating, ion implantation and laser nitriding to form a golden yellow TiN coating on the surface of titanium dentures, thereby improving the wear resistance, corrosion resistance and resistance of titanium Fatigue. However, the technology is complicated and the equipment is expensive.

Nitrogen is a very effective element to improve the wear and corrosion resistance of titanium and titanium alloys by forming the cubic TiN super-hard phase, which in .
This study investigates the effect of plasma nitriding parameters on corrosion susceptibility of PH stainless steel in wt-% NaCl solution. In this regard, PH stainless steel was plasma nitrided at °C for 5 and 10 h, °C for 5 h and °C for 5 h. Nitriding (N) and nitrocarburizing (NC) are thermochemical treatments that diffuse nitrogen and carbon into the surface of metals. Nitriding is used on ferrous, titanium, aluminum, and molybdenum.

Titanium alloys are found in many applications where weight saving, strength, corrosion resistance, and biocompatibility are important design priorities. However, their poor tribological behavior is a major drawback, and many surface engineering processes have been developed to enhance wear in titanium alloys such as nitriding.
Plasma (ion) nitriding, originally developed for ferrous alloys Cited by: 3. Moreover, during the plasma electrolytic nitriding process, a TiN layer with excellent corrosion resistance [28,29] was also produced.
Consequently, the corrosion resistance of the titanium bipolar plates could be further improved by the plasma electrolytic nitriding and annealing treatments. Download: Download high-res image (1MB)Cited by: 5. Titanium and its alloys are commonly used for dental applications because of their excellent corrosion resistance and biocompatibility.1, 2 Their corrosion resistance depends on the formation of a protective oxide layer on the titanium surface, which plays an important role as an inhibitor of ion release.

Padmanabham, in Laser Surface Modification of Alloys for Corrosion and Erosion Resistance, Plasma nitriding. Plasma nitriding is a modern technique for surface hardening of metallic components to improve their service life. Basically, plasma nitriding is a glow discharge process in a mixture of nitrogen and hydrogen gases.
In this study, the effects of plasma nitriding temperature and time on the microstructure, surface hardness, wear and corrosion resistance of quenched and tempered DIN cold work tool steel.
The main aim of this work is to evaluate the effects of the plasma nitriding process on AISI M2 tool steel.
In previous work, treatment time and. Titanium is not in any sense of the word a wonder metal. Take the rigidity and strength of steel, combine it with the ductility of aluminum, the light weight of magnesium, the corrosion resistance of platinum, add creep resistance at high temperature, high impact resistance at sub-zero temperature, blend these together and then, and only then, might we employ the term "wonder metal.".
The passive film on the surface of titanium can be destroyed by immersion in a fluoridated acidic medium. Coating with titanium nitride (TiN) may improve the corrosion resistance of purpose of this in vitro study was to investigate the effect of duplex treatment with plasma nitriding and TiN coating on the corrosion resistance of cast titanium was treated with plasma.
