Sliding mechanism and variable valve timing mechanism for internal combustion engine
摘要：
A sliding mechanism includes a first sliding member made of an aluminum alloy material, the aluminum alloy material being supplemented with at least an element selected from Sb ranging from 0.05 to 0.20 weight %, Na ranging from 0.001 to 0.01 weight %, Sr ranging from 0.001 to 0.05 weight %, and Ca ranging from 0.0005 to 0.01 weight %; and a second sliding member arranged so as to be brought into sliding engagement with the first sliding member. The second sliding member is made of a material which is obtained by caking a rapidly solidified aluminum powder containing therein at least an Si element and a Fe element. Preferably, the Si element has an average particle diameter of 3 μm or less.
