Abstract

PROBLEM TO BE SOLVED: To provide a pachinko ball bard to get dirty and needing less cleanings by diminishing deposition of grounded powder due to wear and grease. SOLUTION: The surface of the main body 1 of a pinball is coated with a diamond-like carbon(DLC) film 2, hence the wear of the surface due to the nail or the collision of the balls with one another in a pinball machine is reduced, and the deposition of the powder shavings is decreased. As the DLC film 2 is formed by plasma CVD, the good-quality film 2 is formed at a low temp. Further, the main body 1 is cleaned with the plasma of at least one kind of gas among a fluorine-contg. gas, hydrogen and oxygen before being coated with the DLC film 2 to remove the contaminates, etc., depositing on the main body 1, and the adhesion of the DLC film 2 is improved.

As described above, the pachinko ball body 1 is DL
The wear amount of the pachinko ball coated with the C film 2 and covered with the DLC film 2 and the pachinko ball composed of the pachinko ball main body 1 not covered with the DLC film (hereinafter, referred to as “untreated pachinko ball”). The amount of oil deposited was examined. Regarding the wear amount, a stainless steel plate made of the same material as the pachinko ball body 1 was used, and the wear amount examined for the stainless steel plate was taken as the wear amount of the untreated pachinko ball. The wear amount of the pachinko ball coated with the DLC film was defined as the wear amount of the pachinko ball coated with the DLC film, and the buffer layer provided on the stainless steel plate and the wear amount of the pachinko ball coated with the DLC film was further measured. Table 1 shows the wear of pachinko balls provided with a buffer layer and covered with a DLC film. The wear amount shown in Table 1 was measured by applying an aluminum rod having a tip curvature of R18 mm to the upper surface of an untreated or treated stainless steel plate as described above.
It is a result of examining the amount of wear when pressing at 00 g and moving for 1 hour at 20 mm / sec.

As shown in Table 2, the amount of oil deposited was 0.35 g in the case of untreated pachinko balls,
0.13 g in the case of pachinko balls coated with. From the above, it can be seen that by coating the pachinko ball body 1 with the DLC film 2, the amount of abrasion and the amount of oil attached could be reduced. Therefore, it is possible to reduce the amount of dirt due to the sliding contact with the ball guide plate in the pachinko machine, the adhesion of powder abraded by the collision of nails and balls, and the adhesion of oils and fats due to contact with hands. Thus, the frequency of cleaning can be reduced.

The conditions for the pretreatment with the O 2 gas and the SF 6 gas were the same as the conditions for the pretreatment with the H 2 gas described above. The adhesiveness was determined by applying an adhesive to a tip of φ5 mm of an aluminum rod and bonding the aluminum rod to a pachinko ball, and then pulling the DLC film to remove the load. Table 3 shows the results.
