Abstract: A method for thermally coating the cylinder barrels of a cylinder block of a combustion engine is disclosed. Air flows through the cylinder bore whose barrel is to be coated. This air flow is generated by means of extraction, whereby the air is extracted from the bottom of the cylinder bore through the crank case of the cylinder block. For extracting the air, a plurality of extraction collars are provided that are connected to an extraction fan and are moved from the bottom through the crankcase to the lower end of the cylinder bores. The pressure of the air flowing through extraction conduits to the extraction fan is measured and the value of the velocity of the air flow through the cylinder bore is calculated. An adjustment mechanism controls air chokes in the air conduits in response to the calculated flow velocity present in the cylinder bores.

Abstract: In order to produce connecting rod bearings which are easier to mount and which are the larger strongly bonded, the large connecting rod eye is plasma-coated with an aluminum-bronze. At the start of the plasma-spraying process, the plasma layer is deposited at a high temperature in order to ensure that the plasma layer bonds well to the connecting rod eye material and has a low level of porosity. In order to prevent the connecting rod eye material from annealing, the depositing temperature of the plasma layer is reduced so that the material to be removed during subsequent finishing is deposited at a lower temperature. After the plasma-coating process is complete, the connecting rod eye is opened by taking off the bearing cover, thus breaking the plasma layer. The cover is then remounted and the bearing surface is finished by fine spindling. The bearing layer has an annular groove in order to improve the oil holding volume. A particularly strong bond between the aluminum-bronze and the connecting rod material can be achieved by multiple sand-blasting of the surface to be coasted with sand particles of increasing grain size.

Abstract: When bearing layers are producing by thermal coating the coating flame causes oxidation of a part of the coating material. To reduce this oxide formation and especially to lower the formation of oxide clusters in the layer a gas stream is projected next to the burner flame with an oxygen content lower than that of air. Preferably a gas with nitrogen ≧99% is used for the gas stream and as cooling gas for the burner. The method disclosed provides a bearing layer for a connecting rod eye. The large connecting rod eye is subjected to pre-spindle trimming, cracking and further spindle trimming to the coating tolerance, sandblasted and plasma coated with an aluminum bronze to produce a microporous layer. At the start of plasma spraying the plasma layer is deposited at a high temperature, which results in good adhesion of the plasma layer to the material of the connecting rod eye and low porosity of the plasma layer. To prevent annealing of the material of the connecting rod eye, the deposit temperature of the plasma layer is reduced during deposition of material which is removed by subsequent machining of the bearing layer. After plasma coating the connecting rod eye is opened by removing the bearing cap, which ruptures the bearing layer. The cap is then remounted and the final bearing surface is formed by fine spindle trimming. To improve the oil retention volume the bearing layer has an annular groove.
