It is significant and necessary to carry out the research and development of self-lubricating bearing. The current study of metal matrix self-lubricating bearing materials is summarized. A new type of high temperature self-lubricating Ti-Al alloy bearing materials is proposed. It is light, anti-friction, anti-corrosion and high temperature resistance (600 °C). The future trend is introduced in the end of this paper.
Phosphor is an important part of the new generation of light-emitting diodes (LEDs), which requires high luminous intensity and high-temperature resistance. In this study, a series of excellent (Ba1-x-yCax)AlSi5O2N7:yEu2+ phosphors...
