X-Ray Investigations Of The Metal Deposits Resulting From The Electrochemical Displacement Process, Cheng Chih Fang

Masters Theses

"The principle of electrochemical displacement has been well established in the science of chemistry and applied as a commercial process in some metallurgical processes, such as the cementation process and the immersion method of metal coatings. According to the EMF series of the metals, the upper, the more electronegative metal,* (*Here the term of 'electronegative' means the metal possessing high electrolytic solution pressure and going into the solution with the formation of positive ions. Some authors preferred to use 'electropositive' instead of 'electronegative', referring to the ions which are electropositive during dissolution.) will displace the lower, the more electropositive one, …
