摘要： An apparatus is provided to reduce the defect rate and decrease production yield by removing foreign objects even when the foreign objects are mixed in with the thermally sprayed film. The operation for forming thermally sprayed film on inner surface of cylinder bore is paused, and protrusions generated in the thermally sprayed film by foreign objects are detected by visual observation and removed by a manual operation. The thermal spraying operation is then performed until thermally sprayed film reaches the prescribed film thickness. After formation of the thermally sprayed film, a finishing operation is performed by means of honing.

摘要： The adhesiveness of a thermal spray coating and a cylinder internal surface is improved by forming a sufficient roughened surface on an internal surface. A processing roller is installed on the main shaft of a processing device via a pressurizing mechanism. An uneven surface is provided on the external periphery of the processing roller. By pressing the processing roller against the internal surface while the roller rotates and moves, a fine unevenness that corresponds to the unevenness of the roller is formed on the cylinder internal surface. A thermal spray coating is formed on the internal surface where the inner surface has been roughened by forming the above-mentioned unevenness.

摘要： Before a thermally sprayed coating is deposited onto a cylindrical internal surface of a cylinder bore 3a rough surface 13 is formed to increase the adhesion of the thermally sprayed coating. After forming the rough surface is completed, an internal diameter measurement surface that is smoother than the rough surface is formed on an axial end section of the internal cylindrical surface. The internal diameter of the cylinder bore is measured at the internal diameter measurement surface with an internal diameter measuring instrument. An appropriate thickness for the thermally sprayed coating is determined based on the measurement result.

摘要： A boring cutter body (5) is inserted into a circular hole (3) and is rotated and moved in an axial direction, whereby screw-shaped groove parts (11) are formed by using a tool bit (9) provided on a tip end of an outer peripheral portion, and broken surfaces (15) are formed by breaking tips of ridge parts generated by formation of the groove parts (11). Moreover, the groove parts (11) are processed through electric discharge machining using a wire electrode (17) provided to the boring cutter body (5) behind the tool bit (9) in the rotating direction, thereby forming finely roughened portions (41) having more finely roughened shapes than the broken surfaces (15).

摘要： A cylindrical internal surface processing method comprises forming a cylinder bore, roughening an upper section of the bore, depositing coating onto the bore, and machining a lower section of the bore and the coating. The forming of the cylinder bore includes forming the upper and lower sections with the lower section being axially spaced from the upper section and having an axial length greater than zero. The roughening creates a roughened surface such that a radially innermost edge of the roughened surface has an internal diameter smaller than an internal diameter of the lower section. The coating is deposited to cover the upper section and at least a portion of the lower section. The machining forms a tapered portion and a cylindrical portion, a radially outermost edge of the cylindrical portion having an internal diameter larger than that of a radially outermost edge of the roughened surface.

摘要： A cylindrical internal surface processing apparatus has an internal diameter measuring device and a controller. The internal diameter measuring device measures an internal diameter of an internal cylindrical bore formed in a base member to obtain a measurement result of the internal diameter of the internal cylindrical bore. The controller includes a surface roughening control section and a quality determining section. The surface roughening control section controls operation of a surface roughening equipment to form a rough surface section and an internal diameter measuring surface section on the internal cylindrical bore. The internal diameter measuring surface section is smoother than the rough surface section. The quality determining section determines if the rough surface section is acceptable to allow a subsequent thermally sprayed coating to be applied on the rough surface section based on the internal diameter measurement result at the internal diameter measuring surface section of the internal cylindrical bore.

摘要： The disclosure relates to surface roughening methods in which a cutting tool having a radial cutting blade with first and second cutting edges is fed along a longitudinal axis of an article while rotating the cutting tool about the axis. The first cutting edge forms a first machined pattern of peaks and valleys on a surface of the article, and the second cutting edge removes at least a portion of the peaks to form roughened fracture surfaces in a second machined pattern defining an arrangement of grooves, corresponding to the valleys, separated by lands, corresponding to the roughened fracture surfaces. The first and second walls may include concave regions within the grooves. The disclosure also provides cutting tools useful in practicing the methods, and cylindrical articles having interior or exterior surfaces roughened using the methods. The methods may have applications to fabrication of cylinder blocks for internal combustion engines.
