Introduction
Lubrication Gradient Materials, otherwise known as LGM, is a specialized class of materials which are designed to improve the performance of sliding components when exposed to high loads, speeds and temperatures. The materials are fabricated from a combination of highly lubricious and wear resistant materials, such as ceramics and technological metals. As such, LGM makes for an ideal component in the manufacture of bearings, gears and automotive components.
Overview
LGMs are made from a mixture of materials, usually with a base of either a polymer or an alloy. Other materials such as ceramics or lubricants are then added to give extra lubricity and wear resistance. The result is a material that has superior performance characteristics compared to traditional materials.
LGMs are produced using a wide range of manufacturing techniques. One of the most common processes is casting, which is the process of pouring molten metal into a mould and then cooling it. This process allows for the formation of complex shapes, which can be tailored to the specific requirements of the component.
Other processes include powder metallurgy, sintering, moulding and injection moulding. All of these processes allow for the addition of other materials, such as ceramics, to give extra strength, wear resistance and lubricity.
There are two main categories of LGMs: reinforced and non-reinforced. Reinforced materials have a reinforcing agent, such as carbon fibres, added in order to give extra strength and wear resistance. Non-reinforced materials only use a single material, such as a ceramic, to give extra strength and wear resistance.
LGMs have numerous advantages over traditional materials. Firstly, as they are made from a combination of materials, they are able to provide better performance at higher speeds and temperatures. Secondly, they are often lighter than traditional materials, which reduces the stresses experienced by components and gives better fuel economy. In addition, they offer improved lubricity and a longer lifespan, resulting in reduced maintenance costs.
Conclusion
In conclusion, Lubrication Gradient Materials are a specialized class of materials specifically designed for improved performance in sliding components. They are made from a combination of materials, usually with a base of either a polymer or an alloy, and are capable of providing better performance at higher speeds and temperatures. Furthermore, they often offer improved lubricity and a longer lifespan, resulting in reduced maintenance costs. As such, LGMs are an ideal choice for manufacturers of lubricated components.
