Benefits of technology
This patented technology describes two benefits - one being better protection against rusting from certain substances than traditional methods like plasma coats or greases on metal surfaces while also reducing damage caused during use over time without losing their effectiveness due to insufficient lubricity between them. Another benefit is making sure there are no residual reactive materials left behind after treatment for some applications such as electronic devices.
Problems solved by technology
This patented technical problem addressed by this patents relates to developing an improved type for mechanisms such as hydraulically driven machines where they require tightly packaged components like bearings due to environmental factors (e.g., humidity). These environments can cause damage from heating up while operating at very fast speeds. To solve these issues, there needs better ways to prevent leakage between different layers within the machine's housing.

Abstract
The invention relates to a composite material for a ceramic sealing ring and a preparation method thereof, relates to a composite material and a preparation method thereof, and is used for solving the problems that the traditional ceramic sealing ring does not have the characteristics of corrosion resistance, wear resistance, low friction coefficient and thermal impact resistance. The first scheme is as follows: the composite material is composed of 5-15 parts of graphite, 80-90 parts of silicon carbide and 5 parts of silica fume by volume. The second scheme is as follows: the preparation method comprises the following steps: (1) uniformly mixing graphite powder and silicon carbide powder in a ball milling tank; (2) pressing in a steel mold to obtain powder green compact of the sealing ring, wherein the pressure is 150-200 MPa; (3) infiltrating the powder green compact in molten silicon liquid for 1-3 hours, applying 0.5-10 MPa argon gas pressure on the surface of the molten silicon liquid during the infiltration process, and taking out infiltrated powder green compact; and (4) sintering the powder green compact in a sintering furnace at the temperature of 1700-1800 DEG C for 2-5 hours. The composite material is used for manufacturing the sealing ring.
