不十分であり五た４５チを越えると粗大な初晶の相がＡ
度に析出し所櫓の耐摩耗性が得られない。To explain the wear-resistant alloy of the present invention in detail, this alloy is characterized by weight ratio of 10 to 45% chromium, 5 to 30% vanadium, 20% or less molybdenum, and the balance nickel. The reason for selecting the composition as described above is as follows. Chromium is a necessary component to strengthen corrosion resistance and the matrix of the alloy.If the composition ratio is less than 10%, the effect will be insufficient, and if it exceeds 50%, the coarse primary crystal phase will become A.
Due to the precipitation, the wear resistance of the tower cannot be obtained.

もよい。Vanadium is a component that reacts with nickel and contributes to strengthening the base of the alloy and improving wear resistance, but if the amount is less than 5%, the effect is insufficient, and if it exceeds 30%, the toughness decreases. This is because molybdenum contributes to corrosion resistance (improvement of M), strengthens the alloy matrix, and improves wear resistance, but the toughness of the alloy decreases after 20 mm This is because boron (0.01 to 2.0 weight i+1) may be added as an element that improves the flow and pourability during melting, strengthens the alloy matrix, and contributes to improving wear resistance.

もので時間当シの体積減少量を示すものである。After melting and casting an alloy with the composition shown in Table 1 using a high-frequency vacuum induction melting furnace, a test piece was cut out from this molded product and subjected to cavitation erosion tests using an ultrasonic vibration method and an Amsler type test. A wear test was conducted to evaluate the characteristics.The cavitation erosion test was conducted for 3 hours in accordance with the JSPS method.The results are also shown in Table 1.The amount of wear in Table 1 is due to wiping. The value obtained by dividing the weight loss (mg) of the test piece by the test time (minutes) and the density (g/-11>) multiplied by 1x106 indicates the amount of volume loss per hour.
