一部が厚肉となると回転軸の作動に支障をきたす。The hard chrome coating (hard chrome plating) formed on the rotary shaft in this manner has the following problems. Hard chrome plating is done by electroplating. This electroplating uses a DC rectifier to deposit the metal ions of the plating solution in the plating bath on the product on the anode, that is, on the rotating shaft. According to such electroplating, the current density around the protrusion of the product tends to be higher than the current density of the recess, so that a thick coating is formed on the protrusion and a thin coating is formed on the recess. Looking at the conventional rotary shaft, the rotary shaft is provided with a notch step portion for attaching the butterfly valve, a notch groove, and a screw hole for screwing the butterfly valve onto the rotary shaft. If the above-mentioned hard chrome coating is formed on the rotating shaft by electroplating, an abnormally thick coating will be formed on the edge part formed by the notch step, the notch groove, and the screw hole of the rotating shaft. It interferes with the operation of the valve. That is, the rotating shaft, a relatively small gap in the bearing hole,
For example, the bearing is supported with a minute gap of about 0.05 mm. (The bearing of the rotating shaft in the minute gap prevents the air from entering into the intake passage from this surrounding gap and causes a small amount of air. If a part of the rotating shaft becomes thick, it will hinder the operation of the rotating shaft.

することになる。Further, according to electroplating, the thickness of the coating film formed on each rotating shaft varies due to the difference in the location of the rotating shaft in the plating tank. That is, the plating film varies among products of the rotating shaft.
Based on the above, after forming a hard chrome coating on the rotating shaft, it is necessary to round the thick parts of the edges and edges, or to remove the plating of the thick parts, and finally to make all the rotating shafts I had to go through the inspections and make a pass / fail decision. In this way, modifying the thick-walled part and performing 100% inspection after the plating process increase the manufacturing cost of the rotary shaft, and in addition, defects in this inspection increase the damage cost. Not preferable. Also, the surface of the hard chrome plated film has a pointed shape, and it is necessary to buff the surface of the rotating shaft to improve the operability, which also causes a high manufacturing cost of the rotating shaft.

軸の表面に超微粒ダイヤモンド被膜が形成される。Then, a method for coating the surface of the rotating shaft with this ultrafine diamond will be described. Ultrafine diamond particles are added to an electroless plating solution, for example, an acidic plating solution, and the rotary shaft is immersed in the plating solution. According to this, the metal ions in the plating solution are deposited as nickel and phosphorus metals by the chemical reaction of the reducing agent, and ultrafine diamond is co-deposited in the deposited metal, and ultrafine diamond is deposited on the surface of the rotating shaft. A film is formed.

動性を大きく向上できたものである。Since the ultrafine diamond coating is formed on the surface of the rotary shaft in this manner, the surface hardness of the rotary shaft can be made at least equal to or higher than that of the hard chrome plating, and at the same time, the hardness can be made extremely high. Since the fine-grained diamond forms a round sphere with an extremely small diameter, generation of scratches is suppressed, and a rotary shaft with excellent wear resistance can be provided. Further, the fact that the ultra-fine-grained diamond forms a rounded sphere greatly reduces the friction coefficient and greatly improves the operability of the rotating shaft.

Even if B and 6B are formed and end portions or edge portions are formed by them, by immersing the rotary shaft in the plating liquid, all the portions including the end portion and the edge portion of the rotary shaft are made uniform with the plating liquid. Since it can be brought into contact with, the ultrafine diamond particles can be uniformly coated to the same thickness on all portions of the rotating shaft. This can eliminate the need for secondary processing of the rotary shaft after coating.

There is no need to carry out secondary processing such as buffing to do so.

減に寄与する。As described above, according to the rotary shaft of the vaporizer of the present invention, the rotary shaft is made of a free-cutting metal such as brass and the electroless plating is possible with nickel or phosphorous plating liquid. Rickel, which is added by diamond and deposited by electroless plating, co-deposits ultra-fine diamond in phosphorus and forms a ultra-fine diamond film on the surface of the rotating shaft, resulting in excellent wear resistance, rotation and operability. A good rotation axis can be provided. Further, since the ultrafine diamond film treatment on the rotating shaft is performed by electroless plating, the mutual coating of the rotating shafts can be performed accurately and uniformly, and further, the end portions of the rotating shafts, the complicated shape portions such as the edge portions, etc. In addition, since it is possible to form a uniform coating, the secondary processing after the coating treatment is not necessary at all, and the inspection related to the coating is unnecessary, so that the manufacturing cost of the rotating shaft can be significantly reduced. Further, the fact that the material of the rotary shaft is made of free-cutting metal also contributes to the reduction of manufacturing cost.
