Zirocnia Ceramics:
With the popularization of laser technology, laser surface treatment technology is also used as a new surface coating treatment technology to surface coating the frictional contact surface of Si3N4 ceramic bearing. The influence of the number of grain boundary phases: the ceramics with different number of grain boundary phases are selected. Corrosion comparison shows that the corrosion rate is basically consistent at the initial stage of the reaction; as the corrosion progresses further, the corrosion rate diverges, the passivation layer appears, and the more the number of grain boundary phases, the more severe the Silicon Nitride corrosion. Centrifugal grouting The mud is injected into the rotating model, and the centrifugal force generated by the rotating model is used to accelerate the process of the mud dewatering process. The centrifugal grouting has the advantages of uniform thickness and compactness of the body, but the particle size fluctuation cannot be too large, otherwise large particles will be concentrated on the surface of the mold. The uneven distribution, resulting in uneven body and inconsistent shrinkage model speed depends on the size of the product. Hot pressing sintering (HPS) is the Si3N4 powder and a small amount of additives (such as MgO, Al2O3, MgF2, Fe2O3, etc.) Pressure forming at temperatures above 1916 MPa and temperatures above 1600 °C for sintering in the UK and the United States The hot-pressed sintered Si3N4 ceramics used in the company has a strength of up to 981 MPa. The addition and phase composition have a great influence on the properties of the product. Due to the strict control of the composition of the grain boundary phase and the appropriate heat treatment after sintering of the Si3N4 ceramic, Therefore, the strength (up to 490 MPa or more) can be obtained even at temperatures up to 1300 °C.
