Hello, this is SGO . 

The SEM test was conducted in cooperation with Sungkyunkwan University and other institutes through the last sintered material sample. With the ingredients from the results (though it is difficult to disclose the data), we tested with the pins in the photo below and the plate being made.

​

Plate processing is easy to manufacture with a processing method that is currently pending a patent in our company, but it is difficult to process pins with a size of Φ5-6. So I made the drawing first, and in consultation with the process manager, I produced a separate specimen as shown in the picture below.

​

Sintering works to increase lubricity by leaking oil encroached inside the pores, but as  in the existing process, there were various problems such as oil not leaking out or easily damaged during production.

This product is a specification requested by advanced company, and a specimen was produced for testing the product under development.

​

The entire process, from processing to impregnation, was produced in a different way than before.

As shown in the picture, research is being conducted, and even though the amount of oil flowing through the pores in the 6-hour test does not appear to be greater than the amount flowing through the pores, the coefficient of friction is very good at 0.17 (0.25 standard).

​

In the first picture above, the red square box part (sintered part) has lubricant inside. Even when the test condition reciprocated at a very high speed of 60 rpm and the friction wear was measured, only a small amount of oil leaked as shown in the picture below . 

The reason why only a small amount of oil is leaked is because the lubricant is made of high viscosity  even though fast speed + friction heat occurs in the product under development, and this  high viscosity lubricant is also applied with a sample under development by our company .

​

As soon as the test is completed, plate products and bearing products will also be tested.
