提供具有弹性模数梯度涂层之基板的方法及设备;METHODS AND APPARATUS PROVIDING A SUBSTRATE HAVING A COATING WITH AN ELASTIC MODULUS GRADIENT

摘要

方法和设备提供：具有第一与第二相对表面和弹性模数的基板；及至少一层，该层在层的第一与第二相对表面之间具有一厚度，耐刮层的第一表面接触基板的第二表面，从而形成界面。该层可展现以下一或更多者：在接近层的第一表面为第一弹性模数且在接近层的第二表面为第二弹性模数，第二弹性模数实质大于弹性模数值，第一弹性模数小于基板的弹性模数，第二弹性模数大于基板的弹性模数，及层展现从第一弹性模数增加到第二弹性模数的弹性模数梯度贯穿层厚度。; and layer(s) having a thickness between first and second opposing surfaces thereof, the first surface of the scratch resistant layer contacting the second surface of the substrate, forming an interface. The layer may exhibit one or more of: a first elastic modulus proximate to the first surface thereof and a second elastic modulus proximate to the second surface thereof, the second elastic modulus being substantially higher than the elastic modulus value, the first elastic modulus being lower than the elastic modulus of the substrate, the second elastic modulus being higher than the elastic modulus of the substrate, and the layer exhibiting an increasing elastic modulus gradient through the thickness thereof from the first elastic modulus to the second elastic modulus.
