Galvanic gold plating for fixed dental prosthesis
Metal ceramic partial fixed dental prostheses have been commonly used for the replacement of missing teeth for many years. Because of an increase in the price of gold, base metal alloys have been the choice of alloy for the fabrication of metal ceramic restorations in many dental clinics. Some major disadvantages of base metals are their corrosion and the dark coloration they may cause at the c...
متن کاملStudy of porosity and voids in dental gold castings.
The problem of voids and porosity has long plagued the dental technician. Many times an otherwise acceptable casting has had to be discarded because voids or porosities have developed within the casting. Because of numerous variables a technician often does not know the cause of the casting failure. Many investigators have studied variables that may affect the occurrence of voids and porosities...
متن کاملEstimating the Effects of Gold Plating Using Fuzzy Cognitive Maps
The systems and software development industry is characterized by a paradigm of project failure. There are various factors that can lead to project failure .One such factor is gold plating. Gold plating can cause various problems in the projects like increase in project complexity, use of more resources, and increase in time and budget of the project and many more. If effects of gold plating ar...

متن کاملAvoiding short circuits from zinc metal dendrites in anode by backside-plating configuration
Portable power sources and grid-scale storage both require batteries combining high energy density and low cost. Zinc metal battery systems are attractive due to the low cost of zinc and its high charge-storage capacity. However, under repeated plating and stripping, zinc metal anodes undergo a well-known problem, zinc dendrite formation, causing internal shorting. Here we show a backside-plati...
