  • Patent number: 10203002
    Abstract: A bearing for an internal combustion engine may include a steel support layer. A coating layer containing a Cu alloy may be laid over the steel support layer. A Ni-based anti-diffusion barrier layer may be laid over the coating layer, and an anti-friction layer containing a matrix of Sn—Zn and Zn precipitates may be laid over the anti-diffusion barrier layer.
    Type: Grant

  • Patent number: 9611803
    Abstract: A piston for an internal combustion engine may include a substantially circular body composed of an aluminum containing base material defining a top portion having at least one cavity. At least one coating layer may be disposed on at least one area defined by at least one of the top portion and the at least one cavity. The at least one coating layer may include at least one chemical compound derived from a chemical reaction between the base material of the body and the at least one coating layer in response to friction generated by a dragging movement of a non-consumable rotary pin with the at least one coating layer.

  • Publication number: 20150345003
    Abstract: A metallic member for a mobile system of an internal combustion engine may include a body defining a crystallographic structure. The crystallographic structure may include an outer layer, a substrate and a saturated zone between the outer layer and the substrate. An external element may be dispersed at least partially through the crystallographic structure of the body. The body may be subjected to a superficial hardening treatment from infiltrating the external element into the crystallographic structure of the body via a laser beam penetrating at least one portion of an outer surface of the outer layer of the body.

  • Publication number: 20150219038
    Abstract: A cylinder liner for an internal combustion engine may include a cylinder. The cylinder may include a first cylindrical portion coupled to a second cylindrical portion. The second portion may be positioned towards a region of combustion in relation to the first portion and define at least in part a combustion chamber. The first portion may include a length at least one half of a length of the cylinder. At least one of the first portion and the second portion may be composed of a ferrous alloy.

  • Patent number: 8646980
    Abstract: A bearing shell segment for internal combustion engines, composed of a body defining an inner surface that receives a coating and makes contact with a layer of lubricant oil film and an opposite outer surface, associable to a bearing, an inner surface having at least a first area substantially free from the compression load coming from the movement of the piston by the explosion of air-fuel mixture, and a second area which receives compression load coming from the movement of the piston by the explosion of air-fuel mixture. The first area has at least a surface portion to capture foreign particles present in the layer of lubricant oil film, the surface portion having cavities positioned so as to enable at least one foreign particle to be captured and withheld while moving towards the flow of lubricant oil, before reaching the second area.
