Patent number: 5928800Abstract: A slide surface construction is formed of an aggregate of metal crystals. The area rate A of hexagonal pyramid-shaped metal crystals in a slide surface of the slide surface construction is in a range of A.gtoreq.40%, and the Co (cobalt) content in the aggregate is in a range of Co.gtoreq.13% by weight. The metal crystals are preferably Fe (ferrous) crystals. The slide surface takes on an intricate aspect due to the existing of a large number of hexagonal pyramid-shaped metal crystals and hence, has a good oil retention. In addition, the wearing of the hexagonal pyramid-shaped metal crystals is inhibited due to an increase in hardness resulting from the incorporation of Co and therefore, the oil retention is maintained. Thus, the slide surface construction exhibits an excellent seizure resistance.Type: GrantFiled: April 1, 1996Date of Patent: July 27, 1999Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yusuke Toyoda, Masamune Tabata, Kenji Dosaka, Takahiro Gunji, Kenji Hirose
