The process of heat treatment operations is quite common in the metallurgy industry. Since different metals and materials need to be required in certain properties, this process helps in making metals hard or soft depending upon the varied requirements. Now coming into the scenario for bearings, the bearings come in contact with hard metals which increases the risk of wear and tear resulting in breakdown or decrease in the service life of bearings. To harden the bearing and make it capable of bearing the thrust, weight and friction of other metals, the hardening process is followed through heat treatment to make it apt for all conditions and applications. The bearings are used in various types of machinery and mechanical systems to reduce friction. As they need to be perfect in shape, size, precision, and quality, the heat treatment operation makes it worthwhile to be used in any application under the toughest conditions.
How Heat Treatment Operation is PerformedThe heat treatment operation involves various processes which are aimed towards achieving certain results. Here are some of the points which precisely explain it:
- Heating material under tight controls and specified temperature.
- Holding temperature as per the specific time duration to achieve desired results.
- Performing slow cool to fast cool while following varied methods.
Hardening Bearing to Improve its Strength – Why is it used?The bearings should have desired strength to achieve optimum performance without any failures. To make it work in extreme conditions, there is a need to harden its surface to reduce friction while coming in constant communication with surfaces of other materials. To understand it better, machines may contain various components and bearings are fit in between them to reduce friction. To make the bearing perform in an optimum manner, it is crucial that it withstand a hardened surface.
Types of Hardening Process for Bearings in Heat Treatment OperationsThe hardening process is quite crucial for bearings. Here are different types of hardening processes that are performed in heat treatment operations:
- Case Hardening
- Induction Hardening
- Through Hardening
