Abstract
A metal matrix composite to high tolerate wear as a property has been produced by infiltration casting of a Fe Alloy and a spinel ceramic by using a material design for i) metal transport phenomena conditions, ii) predefined wetting and capillarity and iii) processing child insert/mother casting methodology to produce a final casting in shape and form to meet the needs of a mining end user.
Claims13
A casting method of producing a wear resistant mining casting material, said method comprising:
- (1) selecting an Fe alloy metal and a spinel ceramic each having a Coefficient of Thermal Expansion (CTE), a wetting contact angle (WCA), or a combination thereof;
- wherein the Fe alloy metal has a CTE of from about 10 ppm° C.−1 to about 21 ppm° C.−1 and the spinel ceramic has a CTE of from about 6 ppm° C.−1 to about 11 ppm° C.−1;
- and
- wherein the Fe alloy metal and the spinel ceramic have a WCA of <90°;
- (2) manufacturing by an infiltration process a child metal insert casting comprising the compatible Fe alloy metal and the spinel ceramic;
- and
- (3) placing the resultant child insert casting into a mother holding casting for specific design and locations using mechanical fixing chaplets before final Fe alloy metal pouring and solidification of a product.
