Process of gold plating with vibration for stainless steel spring needles;

A new activation process as pretreatment of citric gold plating and its workshop applications;

micron gold deposit was obtained on TO series tube socket with the title process in which nickel electrodeposit was used as barrier base, and strike gold deposit was subsequently applied, then pulse gold electroplating in sulfite solution was adoopted to deposit gold top.

A new direct gold electroplating porcess for steel products is presented such us human-being contacting consumer goods and cooking utensils.

A series of measures to guarantee the electroplated gold layer’s weldability were presented,including changing the welding wire hole’s structure design,improving the gold electroplating process and managing the post-plating methods of gold electroplated pieces reasonably.

Application and research progress of gold-plating on improving non-precious metal corrosion resistance

Methods To measure the quantity of beryllium ion which was released from common used Ni-Cr porcelain crown(controlling group),polished Ni-Cr porcelain crown(polished group),gilded Ni-Cr porcelain crown(gold-plating group) and gilded Ni-Cr porcelain crown prolonged 50%(gold-plating prolonged 50% group) in artificial saliva after 1 month,3 months and 6 months by means of ICP-.

To study the effect of surface treatment such as titanium nitrogen(TiN) coating and gold-plating on corrosion resistant of Ni-Cr alloy and Ni-Cr Alloy With Titanium.

Au electroplating on gold alloy parts was described as well as pretreatment and operation hints.
