A protective masking device adapted to rest on the upper surface of an engine block having cylinder bores during a thermal coating operation of the cylinder bores comprises a protective masking member having an essentially hollow cylindrical shape with an inner diameter selected in relation to the diameter of the cylinder bore to be thermally coated. The protective masking device comprises either an essentially tube shaped outer sleeve member and an insert member inserted into the outer sleeve member, or it is designed such that at least a portion of a layer or of several layers of coating material applied to the inner side of the masking device during the coating operation of the related cylinder bore is mechanically removable. Using the proposed masking device, the coating operation can be started outside the cylinder bore, without the danger that portion of the engine block or the environment is contaminated by coating particles.
A protective masking device adapted to rest on the upper surface of an engine block having cylinder bores during a thermal coating operation of said cylinder bores, comprising a protective masking member means having an essentially hollow cylindrical shape with an inner diameter selected in relation to the diameter of the cylinder bore to be thermally coated.
A protective masking device assembly adapted to rest on the upper surface of an engine block having cylinder bores during a thermal coating operation of said cylinder bores, comprising at least two protective masking member means each having an essentially hollow cylindrical shape with an inner diameter selected in relation to the diameter of the cylinder bores to be thermally coated.
A method of thermally coating the cylinder bores of an engine block, comprising the steps of:
