Analysis on the Development Trend of Powder Metallurgy in the Field of Energy Saving and Emission Reduction Automotive Parts

At present, the powder metallurgy parts used in automobile manufacturing are mainly self-lubricating bearings containing metal oil and powder metallurgy structural parts. From the birth of powder metallurgy technology to the early 1960s, most of the automobile P/M parts produced by powder metallurgy technology are metal oil-bearing self-lubricating bearings.

With the progress of technology and the continuous improvement of the performance of powder metallurgy parts, since 1965, the development speed of powder metallurgy structural parts has far exceeded that of sintered metal oil bearing. At first, most of the P/M structural parts used in automobiles were concentrated on engines and transmissions, mainly parts with complex shape, high density, high strength and high performance. For example, engine connecting rod, camshaft, bushing, gear, ring gear and other parts

Powder metallurgy technology has the advantages of saving raw materials, light weight, excellent performance and low cost. In addition to engine, transmission and motor bearing, powder metallurgy parts are now used by more and more vehicles, and more parts are used in chassis, body, interior, etc., The prospect is very broad.

At present, more than 1000 kinds of powder metallurgy parts have been used in automobiles. Some insiders pointed out that powder metallurgy structural parts have unique advantages in replacing existing gears, cams, sprockets, castings of various shapes, forgings, machined parts and developing new structural parts.

In recent years, due to the excessive use of high carbon energy, extreme weather occurs frequently, bringing serious disasters to human life. In order to achieve the goal of harmonious coexistence between man and nature, it is necessary to change the existing lifestyle, save energy, reduce carbon dioxide emissions, protect the ecology, and welcome the arrival of the low-carbon era. New energy vehicles are gradually being used. As an important part of new energy vehicles, powder metallurgy components are also developing towards the goal of energy conservation and emission reduction.
