Refractory interface coating for bi-metallic automotive products and method

A vehicle comprising:

• an automotive product including:
• a first component of a first material including:
• an annular portion having at least one friction surface,
• a first flange member having a first surface, a second surface, first flange proximal end and a first flange distal end, the first flange member configured to extend radially from the annular portion, from the first flange proximal end to the first flange distal end,
• a plurality of mechanical engagement features that protrude and extend from the first surface and the second surface;
• a second component of a second material configured to engage the first flange member;
• and
• wherein the plurality of mechanical engagement features are coated with a refractory interface coating;
• a vehicle axle assembly configured to receive and engage the automotive product.

A method of making an automotive product, the method comprising:

• forming a first component, of a first material, utilizing a metal working process, the first component having a plurality of mechanical engagement features;
• applying a refractory interface coating to the plurality of mechanical engagement features of the first component;
• placing the first component in a molding machine cavity;
• creating a second component, of a second material, by injecting molten material into the molding machine cavity to envelop the plurality of engagement features;
• forming an interconnection between the first and second components upon cooling of the molten material.
