    • Diamond electrodes with improved adhesion of the diamond layer to the electrode are produced by sandblasting a surface of the electrode body, and then non-oxidatively etching the roughened (sandblasted) surface so as to remove at least 5 μm of material from under the roughened surface. By removing at least 5 μm of material, the sand particulates in the surface of the electrode body are eliminated, and damage in the form of cracks in the electrode body which result from sandblasting is reduced or eliminated, and further, a surface metal oxide coating is not created. All of these contribute to preparing a surface where spalling of the diamond layer is less likely to occur. Concentrated phosphoric acid is an exemplary non-oxidative etchant used in the process.
    • 金刚石层与电极的附着力提高的金刚石电极是通过对电极体的表面进行喷砂,然后非氧化蚀刻粗糙(喷砂)表面,从而从粗糙表面下面除去至少5微米的材料 。 通过除去至少5微米的材料,消除了电极体表面的砂粒,减少或消除了由喷砂造成的电极体中的裂纹形式的损伤,此外,表面金属氧化物涂层 没有创建 所有这些都有助于制备难以发生金刚石层剥落的表面。 浓磷酸是本方法中使用的示例性非氧化蚀刻剂。

    • A gemstone is provided and has a large surface-area, plate-shaped support having a surface with least one pyramid-shaped depression. A thin vapor phase deposit layer comprises a thin, surface-shaped precious synthetic gemstone layer disposed on the large surface-area, plate-shaped support and has an upper surface facing away from the plate-shaped support and an underside having at least one pyramid-shaped projection disposed in and coinciding with the pyramid-shaped depression of the support. Side faces of the pyramid-shaped projections of the underside of the vapor phase deposit layer upon the plate-shaped support impart decorative, diamond-light-reflective qualities to the synthetic gemstone layer.
    • 提供了宝石,并且具有大的表面积的板状支撑件,其具有至少一个金字塔形凹陷的表面。 薄的气相沉积层包括设置在大表面积的板状支撑件上的薄的表面形状的珍贵的合成宝石层,并且具有背离板状支撑件的上表面和具有至少一个金字塔 该突起设置在支撑体的金字塔状的凹部中并与其一致。 在板状支撑体上的气相沉积层下侧的金字塔形突起的侧面赋予合成宝石层装饰性的金刚石光反射性质。
