It is preferable to set the content to 0% by weight and to perform an age hardening treatment.

本発明において、Ｎｉ−Ｗ合金めっき中にＳｔ、Ｎ４の
硬質粒子を分散共析させる理由は次の通りである。In the present invention, the reason why hard particles of St and N4 are dispersed and eutectoid during Ni-W alloy plating is as follows.

ため、本発明の分散共析させる硬質粒子とした。As a result, as shown in Figure 3, in the case of a mating material made of gray cast iron (Fe12) equivalent to a cylinder, those with excellent wear resistance will have more wear resistance, and those with less wear resistance will have less wear resistance. There is a tendency to be inferior, and in that, 5if
Since fN4 hard particles can substantially satisfy both requirements, they were used as the hard particles to be dispersed and co-deposited according to the present invention.
以下、上記で行った摩擦摩耗試験（試験１という）につ

。In addition, the reason why the W content in the Ni-W alloy plating was limited to 30 to 50% by weight is that the W This is because if the content is less than 30% by weight, the wear on itself will increase, and if it exceeds 50% by weight, it will be impossible to obtain a dense plating, and the wear on itself will increase. The sample used for the test was made of Fe12 as the mating material, SK5 as the bottle base material, and had the same shape and finish as Test 1. The details of the plating are shown in Table 2.
As shown. The wear test conditions were also the same as Test 1.

１と同じである。(Margins below) Table 2 Plating contents of the sample materials In addition, the composite ratio of hard particles of Si and N is 5 to 35% by volume.
The reason for this is that when the composite ratio of 5izNn is less than 5% by volume, its own The wear resistance is insufficient (if it exceeds 35% by volume, the plating film becomes hard and brittle, causing hard particles to fall off, which not only accelerates the wear of the other but also increases the wear of itself). In addition, the mating material of the sample used in the test was Fe25, and the shape and finish were the same as in Test 1. The base material, shape, and finish of the bottle were the same as in Test 1. The plating contents are shown in Table 3. The wear test conditions are also the same as Test 1.

This is because when the particle size of 5rzNs exceeds 3 μm, wear of the mating material increases. In the sample used for the test, the mating material was Fe25, the pin base material was SK5, and the shape and finish were the same as in Test 1. The plating contents are shown in Table 4, and the wear test conditions were also the same as Test 1.
