it has been taught previously in the literature that a low friction coating on the stand off is beneficial to reduce friction and wear between the two surfaces however at the same time it would be beneficial to mechanically anchor the stand offs to the glass so that the glass can be handled during manufacturing without any stand offs falling off of the glass these two constraints u2014 both low friction and mechanical anchoring u2014 are diametrically opposed and thus there has not previously been a solution that allows both mechanical anchoring and low friction it is thus surprising to note that thin films of low melting temperature alloys particularly those containing indium or bismuth anchor effectively to glass yet provide for good lubricity this is because of the particular mechanism for friction reduction in these films the materials themselves are actually quite adherent but when they are coated to conform to a first rough surface they will have very little total surface area in contact with any other surface that they are placed against further because these low melting alloys have low shear strength they will fail cohesively when rubbed allowing for easy sliding this combination of low contact area and low strength makes for an ideal lubricant with an exemplary coefficient of friction of 0 1 or less however when.
