Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. Heat treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming. Heat Treatment is often associated with increasing the strength of material, but it can also be used to alter certain manufacturability objectives such as improve machining, improve formability, restore ductility after a cold working operation. Thus it is a very enabling manufacturing process that can not only help other manufacturing process, but can also improve product performance by increasing strength or other desirable characteristics.
Tento proces je špeciálne použité na zlepšenie odolnosti na opotrebenie mierne, holý uhlíka alebo veľmi nízke Legovaná oceľ.Carbonitriding sa vykonáva pri nízkych teplotách v rozsahu 800 až 870 titul ...
Un mediu care este utilizat pentru stingerea este cunoscut ca quenchants.Cel mai frecvent quenchants sunt apă, ulei, săruri, aer, gaze şi soluţii apoase.
Chromizing is also used for surface hardening of both carbon and tool steels.The components to be chromized are packed with fine chromium powder and additives.
Bronizing is one of the recent methods of surface hardening,which may be applied to any ferrous material but is generally adopted for carbon steel and tool steel.
Nitriding is most effective for those alloy steels which contain stable nitride forming elements such as aluminum,chromium,molybdenum,vanadium and tungsten.Nitriding is carried out in a ferritic ...
This process is specifically used for improving wear resistance of mild,plain carbon or very low alloy steels.Carbonitriding is carried out at low temperatures in the range 800 to 870 degree in a gas ...
