  • Method of scale substrate manufacture
    Patent number: 10072943
    Abstract: The present invention relates to a method for producing a magnetic substrate for an encoder scale. The method comprising the step of mechanically working the substrate, wherein the substrate is cooled prior to the mechanical working step. In one embodiment, a stainless steel substrate is used. The stainless steel may comprise an austenite (non-magnetic) phase and a martensite (magnetic) phase. Mechanically working and cooling in this manner increases the amount of magnetic (martensite) phase material that is formed, thereby improving the magnetic contrast when non-magnetic (austenite) marking are subsequently formed on the substrate by laser marking.
