    • Multilayer high transmittance, low emissivity coatings deposited over transparent substrates have improved mechanical durability, e.g. scratch resistance by the inclusion of at least one mechanical durability enhancing layer (hereinafter "MDE layer"). The MDE layer includes one or more pairs of a zinc oxide sublayer having deposited thereover a sublayer of an oxide of zinc and tin. In one embodiment of the present invention, the MDE layer is composed of two sublayers which includes a first sublayer of an oxide of zinc having deposited thereover a second sublayer of an oxide of zinc and tin. In another embodiment of the invention, the MDE layer is composed of four sublayers which includes a first sublayer of an oxide of zinc, having deposited thereover a second sublayer of an oxide of zinc and tin, having deposited thereover a third sublayer of an oxide of zinc, having deposited thereover a fourth sublayer of an oxide of zinc and tin. Coated articles having the MDE layer of the invention can be thermally processed for tempering, heat strengthening, annealing or bending without haze formation and can be manipulated prior to such thermal processing with little or no surface scratching appearing after such thermal processing.
    • 沉积在透明基底上的多层高透光率,低辐射率涂层具有改善的机械耐久性,例如 通过包含至少一个机械耐久性增强层(以下称为“MDE层”)的耐擦伤性。 MDE层包括一对或多对氧化锌层,其上沉积有锌和锡的氧化物的子层。 在本发明的一个实施方案中,MDE层由两个子层组成,这两个子层包括锌的氧化物的第一子层,其上沉积有锌和锡的氧化物的第二子层。 在本发明的另一个实施方案中,MDE层由四个子层组成,其包括锌的氧化物的第一子层,其上沉积有锌和锡的氧化物的第二子层,其上沉积有第三子层的氧化物 锌,其上沉积有锌和锡的氧化物的第四子层。 具有本发明的MDE层的涂层制品可以进行热处理以进行回火,热强化,退火或弯曲而不产生雾度,并且可以在这种热加工之前进行操作,在这种热处理之后几乎没有或没有出现表面划痕。
