Oil Dipping Treatment for Powder Metallurgy Products
Powder metallurgy is a process for making structural and mechanical products. It is the branch of metallurgy which deals with the physical and chemical processes involved in the production of powdered metals and the subsequent powder metallurgy products. The powder is produced from metallic components that are ground up and combined with additives. The powder is then heated until a reaction occurs producing a firm, hard and inert powder. This powder is then pressed into various shapes and sintered, which is the process of heating without melting. The thermal treatment increases the strength of the product to some extent.
For better strength and stability of the parts made from powder metallurgy, an oil-dipping process is done for further protection of the parts. Oil dipping is an application of oil to certain parts of the product in order to protect it from corrosion, abrasion and other damaging effects. The oil provides a physical barrier between the surface of the product and the external environment.
Oil dipping is especially important when the product is exposed to extreme temperatures, high humidity, dust particles and other environmental conditions. The oil coating provides a layer of protection against these elements so that the product remains in the best possible condition and remains stable.
The various benefits offered by oil dipping include:
• Protection against corrosion : Oil dipping helps to form a protective coating around the product which acts as a barrier against water, air and other corrosive elements.
• Protection against abrasion : Oil dipping prevents wear and tear of the product due to abrasion and helps to maintain a longer life of the product.
• Protection from dirt and dust : Oil dipping helps to reduce the accumulation of dirt and dust particles on the surface of the product, thus ensuring its cleanliness.
• Prevention of the accumulation of oils and lubricants on the surface : Oil dipping helps to reduce the accumulation of oils and lubricants on the surface of the product, thus preventing the product from becoming overly lubricated or slippery.
• Improvement of the overall appearance of the product : Oil dipping helps to enhance the appearance of the product and make it look more attractive.
The process of oil dipping involves immersing the product in an oil bath and maintaining the temperature of the bath at a certain level. The product is left in the oil bath for a specific amount of time, depending on the material and product specifications. Generally, the immersion time ranges from twenty minutes to several hours.
The type of oil used in oil dipping process depends on the application and the product specifications. Generally, neutral mineral oils such as mineral spirits, lubricating oils, veggie oils, etc., are used. The temperature of the oil should be maintained at a certain level in order to enhance the effectiveness of the process.
Oil dipping is an essential part of powder metallurgy process, as it helps to protect the product from external factors and increase the strength and stability of the finished product. The process of oil dipping needs to be done carefully in order to ensure that it is done in the correct manner and with the correct oil.
