Abstract
A vehicular brake rotor component made from a Ti base powder alloy which has been 3D printed to a desired shape before one or both of its wear surfaces are coated with a 0.005 to 0.01 inch thick mixture containing about 1-40% chromium carbine. Then the combined product is sintered, machined and double disc ground. Related methods of manufacture of this brake rotor component are also disclosed.
Claims19
A method for making an automotive braking device comprises:
- (a) providing a titanium or titanium alloy powder;
- (b) passing the titanium or titanium alloy powder through a three-dimensional printer to make a preform brake rotor and hub;
- (c) sintering said preform brake rotor and hub to form a sintered brake rotor and hub;
- (d) machining said sintered brake rotor and hub;
- and
- (e) double disc grinding said sintered brake rotor and hub to form said automotive braking device.
