  • Patent number: 9597857
    Abstract: A method for forming a friction coating construction which utilizes the providing of a mixture of molten metal material with abrasive particles dispersed therethroughout in particulant form which is sprayed onto a flexible substrate which is of a metallic material being preferably ductile which is then allowed to harden and cool to allow the molten metal to affix the flexible support layer with respect to the metal material and with respect to the abrasive particles dispersed therethroughout thereby providing an enhanced friction control surface which can optionally include an adhesive layer on the surface of the flexible substrate positioned oppositely from the abrasive particles to allow this layer to be affixed to any subsurface surface which needs enhanced control of the coefficient of friction thereto.
    Type: Grant
