Powder metallurgical materials are materials made directly from several metal powders, or metal powders and non-metal powders, through preparation, pressing and forming, sintering and post-treatment, without melting and casting. Powder metallurgy is a combination of metal metallurgical processes and ceramic sintering processes, it usually has the following processes. Powder Preparation And Compression Moulding The powder

Powder metallurgy products usually refer to products made from metal powders (or mixtures of metal and non-metal powders) through a forming and sintering process. Powder metallurgy products are usually used in a wide range of applications, from general machinery manufacturing to precision instruments; from hardware tools to large machinery; from the electronics industry to motor

With the increasing requirements of environmental protection, lubricants containing metal soaps can no longer be the direction, can be completely removed from the pure organic lubricants into the mainstream. The initial development of pure organic lubricants for the paraffin wax and its variants, due to high molecular weight, its softening point temperature of more than 130

Different kinds of cutting agent containing 0.4% of FC0205 powder were added on the basis of FC0205 powder to compare their effects on material properties. The forming density of the sample was 7.0 g/m³.I. Effect on mechanical properties Impact on cutting performance: TD-3 and TD-4 have greatly improved the cutting performance of the material.Cutting test

1. Basic information Lubricants are being developed with high lubricity to reduce the compression tonnage and release pressure and to compensate for the lack of compressibility of the base powder. However, these lubricants have low melting points and tend to agglomerate during the compounding process, especially when used in hot weather, which limits their use

First, the positioning of powder metallurgy manufacturers gradually established. The positioning of the company in the high, medium, and low-grade commodity markets is gradually established. Companies with considerable size and skills to focus on high-end commodity stores, usually companies or small companies in low-end commodity stores to open competition. This decomposition is conducive to the progress

Spheroidization Rate and Spheroidal Grade of Graphite in Ductile Cast Iron.The spheronization rate and spheronization grade are assessed according to GB/T9441-1988 “Ductile Iron Metallographic Inspection”, which divides the spheronization grade into 6 grades. Firstly, the whole inspected surface is observed, and then, starting from the worst area, 5 fields of view are observed consecutively, and

The development of the auto parts industry is an important related industry of automobile vehicle manufacturing, through the operation and ranking of the global Top 100 auto parts enterprises in 2017 to sum up the situation, Japan as an auto manufacturing powerhouse, in 2017, the number of Japanese enterprises and operating income are ranked first
