Abstract:
A molding machine cylinder comprising a lining layer having a structure comprising 20-50% by area of tungsten carbide particles and 1-10% by area of tungsten-based metal carboboride particles in a nickel-based alloy matrix, and containing 1-7.5% by mass of Fe, can be produced by a centrifugal casting method comprising a first step of heating at higher than 1140° C. and lower than 1200° C., and a second step of heating at 1080-1140° C. after melting the raw material powder.

Claim (Index 2):
The method for producing a molding machine cylinder according to  claim 1 , wherein said alloy powder comprises 0.01-1% by mass of C, 1-5% by mass of B, 2-20% by mass of Cr, 0.2-5% by mass of Si, 0.2-5% by mass of Mn, 2-30% by mass of Co, 0-5% by mass of Cu, and 0-1% by mass of Fe, the balance being nickel and inevitable impurities.
