    • The invention relates to an engraved shaft which is entirely or principally made of an aluminum alloy. A raster surface is created on the cylindrical surface of said shaft. Said raster surface comprises recessed cells having a predetermined volume. A layer of oxide-ceramics is formed on the raster surface by process of electrolytic oxidation, whereby such a layer, which has a depth between 15 and 50 micrometers and a micro-hardness between 700 and 1500 Hv, adequately reproduces the outline of the external surface of the raster. The high hardness and strength of the oxide-ceramic layer enable the raster cells to maintain a correct shape and dimensions for a long time during the use of the shaft. Said oxide-ceramic layer may be additionally impregnated with metal or organic materials so as to further strengthen the raster surface, increase the corrosion resistance thereof and provide it with special properties (oleophilic, absorbent, hydrophobic, etc.) as required in various systems involving the dosed transfer of liquids and suspensions.
    • 本发明涉及一种完全或主要由铝合金制成的雕刻轴。 在所述轴的圆柱形表面上形成光栅表面。 所述光栅表面包括具有预定体积的凹槽。 通过电解氧化的过程在光栅表面上形成一层氧化物陶瓷,由此这种深度在15微米到50微米之间的微层和显微硬度在700和1500赫兹之间,这样一个层可以再现外部的轮廓 光栅的表面。 氧化物陶瓷层的高硬度和强度使光栅单元能够在使用轴期间长时间保持正确的形状和尺寸。 所述氧化物 - 陶瓷层可以另外用金属或有机材料浸渍,以便进一步加强光栅表面,提高其耐腐蚀性,并且根据需要在各种系统中提供特殊性质(亲油性,吸收性,疏水性等) 液体和悬浮液的剂量转移。
