多层滑动轴承
摘要：
本发明涉及多层滑动轴承(1)，其具有由锡基合金组成的滑动层(5)，所述锡基合金包含1重量％和8重量％的Sb，8重量％和20重量％的Cu，和任选至少一种元素Si、Cr、Ti、Zn、Ag和Fe，其中这些元素各自的份额为介于0.1重量％和2重量％之间，且其中全部合金元素的总含量为最多30重量％，并且锡构成余量，其中至少一部分Cu与Sn作为具有50nm最大粒度的富含铜的析出物存在于所述锡基体中，和/或包含选自由Al、Bi和Ni组成的第二组的另外的至少一种其它元素，其中对于这些元素的每种而言，至少一种其它元素的份额为介于0.1重量％和5重量％之间，和其中包含至少一种第二元素组的元素的滑动层(5)采用PVD‑法沉积，如果纳米颗粒的粒度大于50nm的话。
摘要（英）：

The invention relates to a multi-layered plain bearing (1) comprising a sliding layer (5) made from a tin-based alloy, which contains between 1 wt. % and 8 wt. % Sb, between 8 wt. % and 20 wt. % Cu and if necessary at least one of the elements Si, Cr, Ti, Zn, Ag and Fe, wherein the proportion of each of these elements is between 0.1 wt. % and 2 wt. %, the total content of all of the alloy elements is a maximum of 30 wt. % and remainder is formed by Sn, wherein at least a proportion of the Cu with Sn is present as a copper-rich deposit in the tin matrix with a maximum particle size of 50 nm and/or in addition contains at least one further element from a second group consisting of Al, Bi and Ni, wherein the proportion of the at least one further element is between 0.1 wt. % and 5 wt. % for each of said elements, and wherein the sliding layer (5), which contains at least one element of the second element group, is deposited by a PVD-method when the particle size of the nanoparticles is greater than 50 nm.
