Method of making an electronic apparatus casing

摘要

A method for producing an electronic apparatus casing including: a step of forming a copper layer by way of non-electrolytic plating onto a casing body made from a magnesium or magnesium alloy material shaped into a predetermined configuration; a step of forming a nickel layer on the copper layer by way of non-electrolytic plating; a step of carrying out a surface grinding and a honing to the nickel layer; a step of forming a hard transparent glass layer by using a colloid solution containing SiO2 and Na2O; and a step of forming a silica layer on the hard glass layer by using a partially hydrolyzed solution of an organic silicate ester.
