摘要： Surface layer consists of several layers, one layer being a transition layer to a support element. The surface layer comprises a ceramic layer containing a chemically bound metal. The support element is a metallic element and the transition layer contains intermetallic phases made of the metal of the support material and the metal of the ceramic material. An Independent claim is also included for a process for the production of a surface layer comprising applying a ceramic layer to a metallic support element, and carrying out a reaction between the metal of the support element and of the ceramic layer forming the transition layer containing the intermetallic phases.

摘要： Process for separating a bushing from a pipe (2) clamped in a matrix (3) comprises cutting the pipe material along a separating line (20) using a cutting tool and separating the bushing by a brittle fracture produced on application of axial force. The axial application of force is partly produced by penetration of the cutting tool and a radially inward-directed pre-tension is applied along the separating line by the matrix. The pre-tension causes elastic deformation which induces stress tension in the region of the separating line. Preferred Features: The diameter of the cutting tool is less than half of the inner diameter of the pipe.

摘要： The invention relates to a cylinder crankcase made of an aluminum diecasting alloy with at least one cylinder bore which has at least one cylinder liner made of a hypereutectic aluminum/silicon alloy, in which in each case a piston is arranged so as to be axially movable, the piston comprising at least one piston ring, one piston skirt and one piston crown, the piston having, with respect to its movement relative to the piston ring, a top and a bottom dead center. The invention is characterized in that the cylinder liner ends at most 10 mm below the bottom dead center, and edge regions of the cylinder bore below the cylinder liner consist of the aluminum diecasting alloy.

摘要： A hypereutectic aluminium-silicon alloy or aluminium-silicon composite material coating has a heterogeneous structure of an aluminium solid solution, intermetallic phases such as Mg2Si, oxides and (i) silicon precipitates, (ii) embedded silicon particles or (iii) silicon precipitates and embedded silicon particles, the mean size of the primary silicon precipitates or embedded silicon particles being less than 10 mu m, the mean oxide size being less than 5 mu m and the coating being mainly copper-free, i.e. the copper content is less than 1 (preferably less than 0.1, especially less than 0.01) wt.%. Also claimed are processes for producing the above coatings by thermal (especially atmospheric plasma) spraying with parameters adjusted for formation of oxides. Preferably, the spraying material has the composition (by wt.)

摘要： A method for fitting a cylinder liner into an engine block casting has the bottom lip of the liner cut with a wave form profile. This provides minima (11) and maxima (8). The liner is supported via the maxima on a profile (14) of the casting system. The cast metal reaches into the recesses formed by the profile to form support lips in the profiles. This prevents the cylinder pressure, and piston drag, displacing the liner towards the crankcase. No other fittings are required to secure the liner.
