METHOD OF MAKING MIRROR FOR X-RAY TELESCOPE |
摘要 |
FIELD: physics.SUBSTANCE: method includes electroplating an aluminium alloy workpiece with a nickel alloy and finishing the working surface of the workpiece by polishing to the required roughness in several steps on a polishing stand using an abrasive composition. Dispersion of the abrasive composition is reduced at each subsequent step and a resin is used as the abrasive composition at the last step. The nickel alloy coating is removed after polishing and a reflecting layer is deposited on the inner surface of the coating.EFFECT: providing the required smoothness of the working surface of a mirror coating without meeting strict precision requirements for the polishing tool.1 dwg |
