Electroplating technology

Cells with a small cathode and a large anode are often used in electroplating technology. In this case, a homogeneous distribution of the deposit over the entire cathode is required. 

These commercial heat fluxmeters listed in the Table 19.2 use electrochemical deposition process with electroplating technology, which is a deposition process using electrical current to obtain a metallic layer on a sample s surface. The sample is used as the cathode and the anode is made of the depositing material. As the sample to be... 

The thermocouple of constantan and copper is preferred for the production of conventional heat fluxmeters for different reasons deposition of copper can be done by chemical or electrochemical processes this thermocouple is well suited to electroplating technology because of the higher electrical conductivity of copper (59.1 x 10 S/m) as plots and lower electrical conductivity of constantan (1. 9 X 10 S/m) as a track [51]. 

The thermocouple of constantan/copper (type t) was achieved by an electrochemical deposition of copper to a wire of constantan with electroplating technology. This thermocouple (type t) was chosen for different reasons this type is already confirmed by conventional heat fluxmeters it has good sensitivity for the temperature range we are looking at for physiological applications (0—350°C).

Electroless plating is applicable to the deposition of metals and of alloys. Indeed electroless plating of a Ni-P alloy, developed by Brenner in 1946, was the first example of formation of an amorphous alloy, often referred to as a glassy metal. Since then several methods have been developed for the deposition of different amorphous alloys, both by electroless and electroplating technologies, in addition to metallographic methods of preparing such alloys, which will not be discussed here,...
