パラジウムニッケル層３を３μ形成した。The jewelry 1 made of brass is subjected to normal plating pretreatments such as trichlene cleaning, alkali degreasing and pickling, and then a nickel layer 2 of 3 μm is formed as a base layer by nickel plating, and palladium nickel plating is further applied thereon. Thus, a palladium nickel layer 3 having a thickness of 3 μm was formed.

好ましくない。次にこのメッキに用いたメツキ液の組成
及びメッキ条件を示すと下記の通りである。In this embodiment, the reason why the nickel layer 2 is 3 μ and the palladium nickel layer 3 is 3 μ is that the nickel thickness of the nickel layer 2 is in the range of 1 to 10 μ and the film thickness is 1 μ.
If it is thinner, the effect of corrosion resistance is less, and if it is thicker than 10 μ, the corrosion resistance is sufficient, but it is not preferable from the economical and design standpoint.
The palladium nickel layer of the palladium nickel layer 3 is
If it is in the range of 0.5 to 5μ and the film thickness is thinner than 0.5μ, the effect of corrosion resistance is small like nickel, and if it is thicker than 5μ, it is not economically preferable. Next, the composition of the plating solution used for this plating and the plating conditions are shown below.

At r, a voltage (3.0 KV 50 mA) was applied, plasma was generated and metal titanium was evaporated by a board heating method, and 0.5 μm of a colored coating of the titanium nitride layer 4 was formed on the upper surface of the palladium nickel layer 3 of the accessory 1.

As a gas type, Hl is used as an inert gas, and O 2 , acetylene, methane, or a mixed gas with another gas is used as a reactive gas. The types of metals include metals such as Ta, Zr and Au, and their carbides and oxides.

の３点である。Table 1 shows the results of the corrosion resistance test for 24 hours of artificial sweat immersion performed on the thus-made accessory according to the present invention and the accessory manufactured according to the prior art. still,
The conventional technique shown in Table 1 is completed by forming a nickel layer as an underlayer on the surface of an accessory made of brass and further forming a colored film of a titanium nitride layer on the underlayer by an ion plating method. Traditional accessories and Japanese patent application Sho5
9-51670, and a jewelry layer having a nickel layer formed by plating on the surface of the brass jewelry and a gold layer formed on the nickel layer by plating.

様のぼけ及びダレがなくなり高級感のある外観が得られ
る。As is clear from the above description, by forming the nickel layer / palladium or the palladium alloy / three-color coating on the surface of the accessory of the present invention, corrosion resistance equivalent to that of the gold plating specification can be obtained. The thickness of the nickel layer to 1
Since it is not necessary to make the thickness more than 0 μ, the blurring and sagging of the pattern due to the thick plating are eliminated, and a high-grade appearance can be obtained.
この結果加工精度の高い装身具にも用いることができる
耐食性及び外観のすぐれた装身具を実現することができ
た。As a result, it was possible to realize an accessory having excellent corrosion resistance and appearance that can be used for an accessory having high processing accuracy.
