“…At the same time, it can be seen that with the machining time, the values of the surface compressive residual stresses increase, which is again caused by the hexagonal structure. Compressive stresses dropped for sample 3.11 probably by sliding along the grain boundaries (there was an increase in crystallite size, see [8]).…”

Currently, the extensive research in the field of cutting ceramics is conducted and there are efforts to replace cemented carbides by these materials. However, the problem is to improve the production of ideal compact samples. Therefore, the influence of mechanical machining technologies on the values of macroscopic residual stresses was investigated by X-ray diffraction. The resulting values were discussed depending on machining parameters and surface structure of the studied samples.

This manuscript presents the results of a study on the use of self propagating high temperature synthesis technique combined with direct consolidation for simultaneous synthesis and densification of TiC/Al 2 O 3 composite. The effects of both the mixing procedure of the starting reactant powders, and the addition of different mole fraction of alumina were investigated. The samples were characterized chemically, physically, and morphologically and their mechanical properties measured. It was found that changing the mixing procedure of the starting powders reduced the porosity of the combustion product from 24 to 7 vol%. On the other hand, the addition of 1.0 mol alumina was found to increase the porosity to 13 vol% and hence lower the mechanical properties. However, the addition of alumina resulted in samples with much better geometric definition and therefore this approach should be further investigated with optimized processing conditions.

“…The failure of bearings during the working will affect the accuracy of mechanical system, and even more serious consequences will occur [1]. Compared with steel bearings, ceramic bearings have better wear resistance and higher thermal stability [2,3], so their operation accuracy and reliability are also higher, bringing to a wide application in the fields of high technology. About the performance analysis of high-speed angular contact ball bearings, currently, there are five types of dynamic analytical models for rolling bearings, namely the lumped-parameter, quasi-static, quasidynamic, dynamic, and finite element models [4].…”

This paper focuses on the distribution characteristics of the radiation noise for a full-ceramic angular contact ball bearing (FCACBB). A model for calculating the radiation noise of a FCACBB was established based on the bearing dynamic characteristics and sound radiation theory, and the effectiveness and accuracy of the method were verified by corresponding experiments. The variation of the radiation noise for a FCACBB with the rotational speed was analyzed. The directivity of the sound field in the circumferential direction was found. The variation trends of the radiation noise in the friction load zone and the impact load zone were discussed. The attenuation of the radiation noise in the radial direction and in the axial direction was investigated. The directivity angle and the degree of directivity of the sound field were explored at different radial and axial distances. The results show that the inhomogeneous contacts between the bearing components in the circumferential direction result in different degrees of friction and impact vibration at different locations, which makes the radiation noise of the FCACBB have a larger component in the radial direction than in the axial direction. The conclusions can provide a reference for predicting the radiation noise of FCACBBs and further optimizing the sound field.
