摘要:
The surface-treated material (10) according to the present invention is a surface-treated material including an electroconductive substrate (1) and a surface treatment coating film (2) including at least one metal layer formed above the electroconductive substrate (1), wherein a lowermost metal layer (21), as a metal layer included in the at least one metal layer and formed above the electroconductive substrate (1), is made of nickel, nickel alloy, cobalt, cobalt alloy, copper, or copper alloy, the surface-treated material includes an intervening layer (3) between the electroconductive substrate (1) and the surface treatment coating film (2), the intervening layer (3) containing a metal component of the electroconductive substrate (1), a metal component of the surface treatment coating film (2), and an oxygen component, and the mean thickness of the intervening layer (3) is in the range of 1.00 nm or larger and 40 nm or smaller as measured in the vertical cross-section of the surface-treated material.
摘要:
A wear resistance reinforcing method for a sliding structure formed from at least a pair of components in a sliding relation and provided with a seal member on a sliding face of a first component. A wear-resistant metal-plated film formed from a metal having a predetermined reactivity with the material of the seal member is provided on a sliding surface of a second component. The present invention enables provision of a wear resistance reinforcing method and a sliding structure which improves workability of a film to impart wear resistance properties in addition to low unevenness in wear resistance properties.
摘要:
A plated wire rod material (10) according to the present invention comprises a substrate (1) composed of aluminum or an aluminum alloy, and a surface treatment coat (2) including one or more metal layers and covering the substrate (1). Of the one or more metal layers, an undermost metal layer (21) which is a metal layer formed on the substrate (1) includes nickel, a nickel alloy, cobalt or a cobalt alloy. A mixed layer (3) containing a metal component in the substrate (1), a metal component in the surface treatment coat and an oxygen component is present at an interface between the substrate (1) and the surface treatment coat (2).
摘要:
A coating system for an aluminum component includes a substrate formed from an aluminum material, a zinc or zinc alloy sacrificial layer deposited on the substrate, and an aluminum coating deposited over the zinc or zinc alloy sacrificial layer.
摘要:
A material part (3,28,71,91,110), in particular a metal component made of an aluminium alloy having a slide surface with which another part is slidably contactable is provided with at least a first plating layer (13) of a material having a high wear-resistance. In order to reduce the influence of different thermal expansion and contraction, a fine network of cracks (15) is formed in the plating layer (13).
摘要:
A sliding element has a bearing metallic layer (2) made of aluminium or an aluminium alloy which bears on its side facing the sliding surface a galvanically produced tin layer (4) bonded to the bearing metallic layer (2) by a very thin alkaline, halogen-free layer of zink, copper, nickel and iron immersion deposited (3) on the bearing metallic layer. To produce such sliding elements, a highly-alkaline immersion bath is used containing salts of zink, nickel, copper and iron mainly cyanide-based. After the immersion treatment, the sliding element blanks are rinsed with considerably carbonic acid-free deionised water. During a first tinning step, the sliding element is treated in a bath at a temperature between 20 and 26 °C, with a current intensity from 2 to 3 amperes/dm2 and for a duration of exposure of at least one minute.
