Hi, I am looking for someone to write an article on surface engineering technology Paper must be at least 2750 words. Please, no plagiarized work! Surface hardening techniques can be grouped into two main categories. local thermal treatment and thermochemical processes. The choice of treatment to be used depends on engineering requirement s as well as commercial competition. In this section, this article presents an overview of the procedures used to harden the surface of the steel. Each describes the procedures involved in the two categories.

Engineers modify the local chemical composition of steel at the surfaces by induction of nitrogen, carbon, or both. Sometimes they may also use boron. The techniques used in this category depend on the method of heat treatment applied and can further be broken down into four subcategories:

The most salient features of these processes are the processing temperature, mechanical properties, and depth of the case, as well as the service behavior of the case’s core composite. Temperature is particularly significant because it affects the level of distortion directly.

This can only be done on materials that have already been hardened and tempered. It produces better results when used with a range of alloys of steel that form stable nitrides such as vanadium, aluminum, tungsten, chromium, and molybdenum. The resultant nitrides are dispersed evenly throughout the surface of the steel.

The process occurs at around 540 degrees Celsius where distortion does not take place. The nitride layer on the surface of the metal makes it expand, thus creating large, compressive stresses that in turn increase surface hardness and improve fatigue strength. In addition, the process also results in steel that has a reduced friction coefficient. Nitriding is, therefore, the best method to use when developing surfaces that are intended to minimize friction such as crankshafts and ball bearings.

This process involves the dispersion of carbon atoms into the surface of the metal.&nbsp.
