摘要： The cylinder is made off two cylinders of different hardness. A first hard cylinder (4) is butted (14) against a soft cylinder (6) underneath. The inside diameter of the composite cylinder may be machined to a double cone shape (11), with the butt joint in a gently sloping region. The hone may have two stones (8) on a movable holder (7). The alteration in radius (12) may be between 10 and 100 mu and the conical region may be between 20 and 200 mm long.

摘要： A parting tool for cutting sleeves from tubular material (12) has a rotating cutting disc (8) on a tilt and rotating mounting to cut from the inside of the tube. The angle of the disc is adjustable and the mounting includes an eccentric adjustment. The system has controlled radial and axial pressure to prevent vibration. The tube is clamped (18, 20) with a controlled radial grip. The clamping grip can be used to bend the tube wall, locally in order to obtain a selected cutting angle.

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.) (A) (for coating type (i)) 23-40 (especially 25)% Si, 0.8-2.0 (especially 1.2)% Mg, NOTGREATER 0.6% Zr, NOTGREATER 0.25% Fe, NOTGREATER 0.01% each of Mn, Ni, Cu and Zn and balance Al; (B) (for coating type (i)) as (A) but containing 23-40 (especially 25)% Si, 1-5 (especially 4)% Ni and 1.0-1.4 (especially 1.2)% Fe; (C) (for coating type (ii)) 5-50% Si particles and 50-95% alloy particles of composition (A) but containing 0-11.8 (especially 9)% Si; (D) (for coating type (ii)) 5-50% Si particles and 50-95% alloy particles of composition (B) but containing 0-11.8 (especially 9)% Si; (E) (for coating type (iii)) 5-50% Si particles and 50-95% alloy particles of composition (A) but containing 11.8-40 (especially 17)% Si; or (F) (for coating type (iii)) 5-50% Si particles and 50-95% alloy particles of composition (B) but containing 11.8-40 (especially 17)% Si.

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.
