    摘要： A method of forming an abradable coating includes forming a plasma; introducing a coating material, as a powder having particles in the range between 1 and 50 μm, carried by a delivery gas into the plasma, having a sufficiently high specific enthalpy for at least partially melting some of the powder and vaporizing at least 5% by weight of the powder, to form a vapor phase cloud of vapor and particles; forming a plasma beam by maintaining a process pressure between 50 and 2000 Pa; defocussing the plasma beam by maintaining a process pressure between 50 and 2000 Pa; and forming from the vapor phase cloud an abradable coating, comprising columnar structures. Advantageously, the columnar structured abradable coating has an erosion resistance smaller than 30 s/mils, preferably in the range of 5 to 27 s/mils, more preferably in the range 10-25 s/mils, still more preferably in the range 15-20 s/mils.

    摘要： Cylinder of piston-type internal combustion engine includes at least one bore with inner shell formed from a base material. The base material, in a region of the bore, includes a layer system, and a first boundary surface formed between base material and layer system. Layer system includes at least one thermally sprayed layer forming at least partially a shell surface of the bore and acts there as a functional layer. First boundary surface does not include any profiling applied for mechanical activation of the surface apart from surface roughness resulting from manufacture of the bore. The material of the layer system includes molybdenum and at least one further element in the region of the boundary surface to the base material and is bonded to the base material by a chemical bond. This boundary surface material differs from the material of the functional layer in composition and/or structure.

    摘要： A processing head (1) for surface processing by means of a laser beam is disclosed. The processing head (1) comprises a through passage (2) for a laser having a longitudinal axis (A), at least one powder supply passage (3) and a cooling passage (4) for cooling the processing head (1). The processing head (1) is at least configured of two parts and comprises a body (5) and a sleeve (6). The sleeve (6) is suitable for the arrangement at the body (5). The through passage (2) of the laser and the powder feed channel (3) are configured in the body (5). The body (5) at least partly forms a first sidewall of the cooling passage (4). The sleeve (6) at least partly forms a second sidewall of the cooling passage (4).

    摘要： The invention relates to a method and to a control unit for operating the plasma generation apparatus.The invention is based on a method and a control unit in which a voltage is applied as an ignition voltage between an anode and a cathode for ignition of a plasma.In order to enable a gentle operation of the plasma generation apparatus it is provided in accordance with the invention that a check is continuously carried out during the ignition process whether the ignition of the plasma has been effected. Additionally, the ignition voltage (UZ) is increased starting from an initial ignition voltage (UZA) and after recognizing an effected ignition (at the point in time tZ) of the plasma, the voltage is reduced between the anode and the cathode to a maintenance voltage (UA).

    摘要： Method for coating components by thermal spraying, wherein not the entire surface of the component is to be coated and wherein those parts of the surface that are not to be coated are covered by masking before coating and wherein the covering is made by a paste processes at least in the areas of critical mask boundaries, i.e. by way of a paste dispensed from at least one nozzle, wherein the paste is a curable paste and curing is photo induced and preferably made by way of UV radiation, characterized in that the masking utilizes a partial masking step and a complementary masking step, the complementary masking step being performed at least in the area of critical mask boundaries and the partial masking step being performed in an area spaced from the area of critical mask boundary and the method of partial masking is not a paste process.
