Hard metal peg for antiskid studs in vehicle tyres - where peg is made of carbide(s) bonded by nickel:molybdenum alloy, so good wear resistance is obtd. at reasonable cost

摘要

The peg contains by wt. 6-15% of a Ni-Mo alloy used as a binder for the hard metal carbides; and the Ni-Mo alloy pref. contains 0.66-25.0% Mo. The peg pref. contains simple or complex carbides of elements in gps. IV, V and VI of the periodic system. The pref. material employed for the peg has compsn. 4.5-15% Ni; 0.1-3.75% Mo; 6-15% Ni + Mo; 5-25% TiC and/or NbC; less than 8% TaC, HfC, and/or ZrC; the remainder being WC. The Ni-Mo alloy is less expensive than Co, which is normally used as a binder; and eliminates the need to use reclaimed carbide materials which vary widely in wear resistance.
