ABS作為使用最多的工程塑膠材料，其應用的範圍非常廣泛，生活中隨處可見，不管是家裡的衛浴設備、家具甚至汽車用外觀零件等。
然而射出成形或者擠壓成型的ABS其外觀都缺乏美觀，此時可以透過金屬電鍍的方式，將其賦與接近金屬的外觀及質感，並且維持其材料的可塑性而且重量較金屬輕的特性，此外降低許多金屬所需的成本使其有更高的附加價值。
本實驗先以鉻酸與硫酸適度混合作為進行蝕刻ABS表面的溶劑，使ABS表面變得粗糙，利用錫鈀奈米膠體溶液作為觸媒，再以硫酸鎳、檸檬酸鈉與次磷酸鈉等進行化學鍍鎳，最終使ABS表面覆有一層金屬鎳層，有這層鎳膜後可通過傳統電鍍的方式讓常見的金屬如銅、鎳與鉻鍍在ABS表面上再利用百格測試可證明金屬層有良好的附著力，如此能美化ABS的外觀及耐磨性。

As the most widely used engineering plastic material, ABS has a wide range of applications and can be seen everywhere in life, whether it is home bathroom equipment, furniture or even exterior parts for automobiles.
However, the appearance of injection-molded or extruded ABS lacks aesthetics. At this time, metal plating can be used to give it a metal-like appearance and texture, while maintaining the plasticity of the material and its lighter weight than metal. In addition, Reduce the cost required for many metals to have higher added value.
In this experiment, a moderate mixture of chromic acid and sulfuric acid was used as a solvent to etch the ABS surface to make the ABS surface rough. A tin-palladium nano colloid was used as a catalyst, and then nickel sulfate, sodium citrate, and sodium hypophosphite were used to carry out the electroless nickel plating and finally the surface of ABS is covered with a layer of metallic nickel layer. After this layer of nickel film, common metals such as copper, nickel and chromium can be plated on the surface of ABS by traditional electroplating which can beautify the appearance and wear resistance of ABS and the degree of metal-layer adhesion can be examined by scribe-grid test.
