耗性が得られるものを提供することにある。[Problem to be solved by the invention] When a known composite plating solution is used, the surface of the base metal is coated with a composite film consisting of eutectoid fine particles such as alumina and silicon nitride and a nickel phosphorus compound, and no phosphorus compound is added. Compared to other materials, it has higher hardness and improved wear resistance. However, even if this known composite plating is used, the hardness and wear resistance of sliding parts such as piston rings for internal combustion engines that are subjected to high heat and high loads cannot be sufficiently improved by composite plating unless they are subjected to appropriate heat treatment. The present invention was made to solve this problem, and its purpose is to provide a composite plating film that forms a composite plating film on the base metal surface of piston rings for internal combustion engines, etc. The object of the present invention is to provide a liquid that can obtain sufficient hardness and wear resistance without being subjected to heat treatment.

This is due to the addition of 1 to log/l of boron compound.

In 2), the hardness as plated is low, and a large decrease in hardness occurs at a heat treatment temperature of 300°C. In comparison, the one with poron addition (Example-5) remains plated,
Already shows high hardness and heat treatment temperature 300~3
Since high hardness is maintained up to around 50°C, it can be seen that the addition of poron also contributes to improving heat resistance.

However, when comparing the phosphorus-added film and the poron-added film of Example-5 of the present invention, the poron-added film has higher hardness even as plated, and is more suitable as a sliding member. In addition, when applying a phosphorus-added film to a harsh sliding member, it cannot be used unless it is heat-treated at 350 to 380°C, but the poron-added film of the present invention has high hardness from the beginning and cannot be used without heat treatment. is not necessary, or even if it is, 30
Since the temperature is 0°C, the cost is correspondingly lower.

といえる。(Abrasion Test) The abrasion resistance of Comparative Example-1, Comparative Example-2, and the product of the present invention (Example-5) was evaluated under the abrasion test conditions shown in Table 2. For the wear resistance test, an Amsler type abrasion tester was used, the test piece was a fixed piece, and the mating material (rotating piece) was a donut-shaped (
An outer diameter of 40 mm, an inner diameter of 16 mm, and a thickness of 10 mm was used. It was set so that the formed plating film was in contact with the doughnut-shaped test piece. The test results are shown in Figure 2.
From the results shown in FIGS. 1 and 2, it is clear that addition of poron (B) increases hardness and improves wear resistance. Therefore, the present invention can be said to be the most suitable plating solution for parts that are heated in internal combustion engines and used in harsh sliding environments.

１〜１０ｇ／文であり、最適量は１〜８ｇ／文である。The amount of chemicals used to improve the chemical properties is extremely small. For example, the properties described above can be obtained by adding 0.1 g/l of a poron compound (TMAB, etc.) to the plating solution. However, when the amount of the poron compound added exceeds 10 g/1, the plating stress increases and the film becomes brittle. Therefore, the range of the amount of poron compound added is 0.
1-10 g/sentence, and the optimal amount is 1-8 g/sentence.
