Reaction kinetics heavily influenced by surface condition - an oily surface or one contaminated with cutting fluids will deliver poor results While nitriding is already extensively used in the industry, it is expected to increase further over the next decade.

If you are still finding head lice, then you may want to try the treatment again, depending on the product information. Or, you may want to speak to a pharmacist about different treatment options available. If wet combing has not worked or is not suitable, you could try a medicated lotion or spray. These kill head lice in all types of hair, and you can buy them from pharmacies, supermarkets or online. Cons There's little clinical research into efficacy of treatments, the potential side-effects aren't known and they can be strong-smelling Usually steels are very beneficially treated with plasma nitriding. Plasma nitriding advantage is related to the close control of the nitrided microstructure, allowing nitriding with or without compound layer formation. Not only the performance of metal parts gets enhanced but working lifespan gets boosted. So does the strain limit, and the fatigue strength of the metals being treated. For instance, mechanical properties of austenitic stainless steel like wear can be significantly reduced and the hardness of tool steels can be double on the surface. Plasma Nitriding DiagramInstruction: nitride/nitride harden. If a particular processing medium is required, indicate (ie. gas or plasma).

Thus, nitriding is typically carried out at a process temperature between 500 and 550 °C (930 – 1022 °F) and up to maximum temperatures of 620 °C (1150 °F).

Metallurgically versatile, the ion nitriding process provides excellent retention of surface finish and ensures repetitive metallurgical properties. Ion nitriding can be conducted at temperatures lower than those conventionally employed. The plasma nitriding process does not cause any pollution and insignificant gas consumption which are important economic and public policy factors.
