よって下地表面処理を行なう。The composite cylinder 4 has a material supply hole 5 and a vent hole 6 which are formed by subjecting the cylinder body 1 to end milling and electrical discharge machining. Here, the holes 5 and 6 can be easily and accurately machined not only in a simple circle but also in a complicated shape having the hole function. Next, the composite cylinder 4 whose entire surface except for the holes 5 and 6 is masked is housed in an ion plating vapor deposition tank 8 provided with an electrode 7 of an active metal such as Ti or Zr, and the vacuum is reduced to 10 -3 to 10 -4 . After degassing, for example, 10 volts, with the cylinder 4 as a positive electrode and the evaporation tank 8 as a negative electrode
By plating at 200 to 500 amperes for about 2 hours, the underlayer surface treatment is performed on the hole wall surfaces of the holes 5 and 6 with an active metal of 5 to 10 μm.

Next, the composite cylinder 4 having the base surface treatment is sufficiently washed, and then a solution 9 in which a ceramic having high hardness and corrosion resistance such as SiO 2 and Al 2 O 3 is suspended at 25 to 45% by weight.
Is immersed in an electroless tank 10 containing the aluminum alloy and subjected to an electroless treatment for about 2 to 12 hours to form a ceramic plating layer 11 having a thickness of 5 to 100 μm. Could be obtained.

メッキ層１１を形成して耐摩耗性を向上させている。Referring to FIGS. 2 to 7, there are illustrated various shapes of the supply hole 5 and the vent hole 6 which are different from each other. 3, 5, and 7
It is formed in an extremely high shape in any of the
For this reason, the above-mentioned ceramic plating layer 11 is formed on the hole wall surface of the hole 5 to improve wear resistance.

を向上している。When the screw rotates in the direction of the arrow, the vent hole 6 is formed so as to be narrow in the rotation direction and long in the axial direction, so that the resin blowout is small and a large amount of gas can be absorbed. So, for this,
Since corrosion resistance is required, the above-described ceramic plating layer 11 is formed on the hole wall surface of the vent hole 6 to improve the corrosion resistance.
