Definitions
- the present invention relates to a thermal spray coating formation method for forming a thermal spray coating on the inner surface of a cylinder bore.
- a method in which metal or ceramic is sprayed on the inner surface of a cylinder bore of a cylinder block of an automobile or the like to form a film, and then the surface is smoothed by honing to form a sliding surface of a piston ring is called a thermal spray bore.
- the spray bore is applied as a fuel efficiency improvement technology.
- the cylinder block is heated (this heating is referred to as preheating) before thermal spraying (see Non-Patent Document 1).
- the exhaust flow flowing in and out of the cylinder block cools the inner surface of the cylinder bore, that is, the sprayed surface, and the preheating temperature of the cylinder block is lowered. For this reason, the adhesion of the thermal spray coating to the inner surface of the cylinder bore is reduced.
- the present invention provides a thermal spray coating formation method capable of enhancing the adhesion of the thermal spray coating to the inner surface of the cylinder bore while suppressing the decrease in the preheating temperature of the cylinder block.
- At least one cylinder is sprayed at a distance from at least one cylinder with respect to the first thermal sprayed cylinder bore, and the next thermal spraying is performed.
- FIG. 1 is a perspective view showing the entire thermal spray coating formation apparatus for carrying out the method of the present embodiment.
- FIG. 2 is a view showing the flow of air flow when exhausted by the thermal spray coating formation apparatus for carrying out the method of the present embodiment.
- FIG. 3 is a perspective view showing the thermal spray gun before it is inserted into the cylinder bore.
- FIG. 4 is a schematic view showing how a spray coating is formed by spraying a droplet onto the inner surface of a cylinder bore with a spray gun.
- FIG. 5 is a characteristic diagram showing the relationship between the preheating temperature and the adhesion.
- FIG. 6 is a characteristic diagram showing a change in cylinder block temperature after preheating with respect to the elapsed time of the first cylinder bore and the fourth cylinder bore.
- FIG. 7 is a view showing the order of spraying each cylinder bore.
- FIG. 1 is a perspective view showing the entire thermal spray coating formation apparatus for carrying out the thermal spray coating formation method of the present embodiment.
- the thermal spray coating forming apparatus has a configuration in which a cylinder block 1 and a thermal spray gun 2 for forming a thermal spray coating on the inner surface of each cylinder bore of the cylinder block 1 are disposed in an exhaust casing 3.
- the housing 3 is formed as, for example, a rectangular box having a hexahedron shape.
- casing 3 is not limited to the shape of FIG.
- an intake duct 4 for intake is provided on the left side surface 3a.
- an exhaust duct 5 for exhausting air is provided on the right side surface 3b, the upper surface 3c, and the lower surface 3d.
- Air supplied into the housing 3 is introduced into the air intake duct 4.
- the air in the housing 3 is discharged to the outside of the housing 3 from the exhaust duct 5.
- the air flows around the cylinder block 1 and also flows in the cylinder bores 6 (6A, 6B, 6C, 6D) formed in the cylinder block 1.
- the spray gun 2 is an arc spray gun as shown in FIGS. 3 and 4.
- the thermal spray gun 2 continuously delivers the wire 7 made of a metal material as a positive electrode and the wire 8 made of a metal material as a negative electrode so that they are close to each other at the nozzle tip and supplies an atomizing gas 9 to generate an arc 10. Let Both wires 7 and 8 are melted by the arc 10 to form droplets 11 which are thermal spray particles. The droplets 11 are deposited on the inner surface 6 a of the cylinder bore 6 to form the thermal spray coating 12.
- the adhesion of the thermal spray coating 12 formed on the inner surface 6 a of the cylinder bore 6 depends on the preheating temperature for heating the cylinder block 1 before thermal spraying. As shown in FIG. 5, when the preheating temperature of the cylinder block 1 increases, the adhesion of the thermal spray coating 12 also increases as the preheating temperature increases.
- the cylinder bores 6 formed in the cylinder block 1 of the in-line four-cylinder engine are, from the end, the first cylinder bore 6A, the second cylinder bore 6B, the third cylinder bore 6C, and the fourth cylinder bore 6D.
- the cylinder block 1 is preheated by heating means such as a heater. Then, the inside of the housing 3 is exhausted. Then, an air flow as shown in FIG. 2 is generated. Next, in the order of spraying, the first cylinder bore 6A, the second cylinder bore 6B, the third cylinder bore 6C, the fourth cylinder bore 6D, and the last cylinder bore 6D are sprayed by the exhaust flow. The preheating continues to be taken away. Therefore, as the cylinder bore whose spraying order becomes later, spraying is performed in a state where the preheating temperature is lowered.
- heating means such as a heater.
- the molten metal droplet 11 is sprayed onto the inner surface of the cylinder bore.
- the metal spray 11 is sprayed on the inner surface of the cylinder bore and deposited to form a thermal spray coating 12.
- excess particles 11 or droplets 11 that bounce off without adhering to the inner surface of the cylinder bore are exhausted and discharged from the exhaust duct 5 to the outside of the housing 3. Thereby, quality degradation of the sprayed coating 12 can be prevented.
