Patent number: 9279467Abstract: A method is disclosed for forming a brake rotor including a desired custom marking having a predetermined size and shape. The method includes applying a chemical treatment to a marking portion of a surface of the rotor. The marking portion has a size and shape corresponding to the predetermined size and shape of the desired custom marking. The chemical treatment is configured to affect, in a predetermined manner, an ability of a stimulus, to which the rotor is to be exposed, to alter properties of the rotor. The method also includes exposing the rotor, having the chemical treatment applied thereto, to the stimulus. The stimulus alters properties of the rotor at the marking portion differently than the stimulus alters properties of the rotor at other portions of the rotor adjacent the marking portion, thereby forming physical differences in the rotor, which, being visually perceptible, form the custom marking.Type: GrantFiled: November 28, 2011Date of Patent: March 8, 2016Assignee: GM Global Technology Operations LLCInventors: Michael D.
