Summary of Expertise: Listed with other top experts in: 
COMPOSITE PLATING. Expert's work with composite plating is predominantly involved with many elements, including carbide, silicon, tungsten, titanium and chromium oxide, titanium, aluminum, and zirconium.

Composite plating is a technology to codeposit insoluble metal particles with nickel and copper to improve high-temperature wear resistance, and anti-friction and anti-sizing properties of those metals. Expert is also familiar with copper coating interconnect and via holes of silicon wafers.

ELECTROFORMING GOLD ALLOYS FOR DECORATIVE ARTICLES. Electroforming precious metal and its alloy is for the purpose of reducing the weight of jewelry items, thus making them more affordable. The key to this technology is building a thick coating without internal stress, and with a most-appealing fine-grained surface. Expert has worked with nearly all types of alloys, including Au/Ag, Au/Au/Cu, Au/Cu/Cd, Au/Pd, Au/Cu, Au/Sn, and Au/Ni. His experience in this technology has awarded him many overseas trips where these manufacturing processes are most active.

ADDITIVE PLATING. There are many addition agents used by the metal finishing industries to achieve desired end results. Expert's service in this area is quite extensive. He is thoroughly familiar with brighteners for precious and base metals, chelators for precious and nonprecious, grain refiners such as As, Tl, Se, hardeners such as Co, Cd, Ni, Fe, surfactants such as anion, cationic, nonionic, and reducers such as formaldehyde and hypophosphite.

NICKEL PLATING; BARREL PLATING; BLACK NICKEL PLATING. Expert has extensive expertise in watts-type bath, decorative nickel, barrel plating, high-speed plating, sulfamate and fluoborate processes, and hard nickel and black nickel plating. He is proficient in additives for brightening, leveling, and relieving stress, as well as nickel plating for solderbility of electronics, nickel-electroforming molds and dies, bellow, mirrors, wave guides, and heat exchangers.

ELECTROPLATING. Expert's recent involvements include electroplating chip capaciters and registers with nickel and solder; electroplating silicon wafers with copper, solder, nickel, and gold; and electroplating aluminum memory disk with electroless nickel.

PATINA PROCESS. Coloring copper and its alloys is accomplished anodically, as well as immersion and heating (namely "patina"). Expert's experience in patina has led him to many technical assistance responsibilites to the art industries. In addition, the coloring and patina processes he is able to offer include bath preparation and its applications.
