摘要： A high-pressure pump (1) which serves, in particular, as a radial or in-line piston pump for fuel injection systems of air-compressing, auto-ignition internal combustion engines, comprises a pump assembly (6) and a drive shaft (7) which has at least one cam (10) which is assigned to the pump assembly (6). Here, the pump assembly (6) comprises a roller (31) which runs on a running surface (34) of the cam (10) and a roller shoe (30) which receives the roller (31). Here, at least one anti-corrosion layer is provided on the roller (31) and/or at least one anti-corrosion layer is provided on the roller shoe (30) and/or at least one anti-corrosion layer is provided on the cam (10). This can prevent oscillation crack corrosion occurring during operation, which corrosion can lead under loading to breakouts near the surface and, as a result, to failure of the high-pressure pump.

摘要： The invention relates to a method for determining the quality of layers (4) deposited on substrates (3), in particular of layers (4) deposited on substrates (3) for wear protection, corrosion protection, decoration, photovoltaics, and/or paints and laminates, wherein pulsed light is generated, by means of which the surface of the layer to be examined (4) is scanned in a spatially resolved manner, and a beam (6) reflected by the layer (4) is detected and evaluated in respect of intensity and/or phase and/or polarisation, the laser light being pulsed such that a particular layer section (10) that has been irradiated therewith is heated in a cyclically alternating manner and is cooled at least partially. To this end, the pulse duration of the laser light is selected such that temperature increases at least temporarily in the layer (4) as far as the boundary layer between the layer (4) and the substrate (3) arranged therebelow. The pulse spacing is adjusted such that the layer in the irradiated layer section (10) can cool. The emission wave length of the laser light is selected such that the layer behaves at least partially optically transparently for the incident laser light.

摘要： The high pressure pump comprises a drive shaft (12) with at least one cam (16) or eccentric and at least one pump element (18) with a pump piston (20), driven in the reciprocating direction by the cam (16) or eccentric on the driveshaft (12) in a reciprocating motion. A support element (44) is arranged between the pump piston (20) and the cam (16) or eccentric on the driveshaft (12) and also a roller (46) running on the cam (16) or eccentric is mounted to rotate therein. A support (60) for the roller (46) in the direction of rotation is arranged adjacent to the same in the direction of the rotational axis (47) of the roller (46). The roller (46) and/or the support (60) comprises a surface with high wear resistance at least in the contact region between the roller (46) and the support (60).
