Tarnish and Corrosion

Image
  TARNISH AND CORROSION  TARNISH : S urface discoloration  on a metal /even slight loss of surface finish. CORROSION:  D eterioration of a metal by reacting with environment,water ,oxygen,chloride ion,sulfide contribute corrosion attack. CAUSES FOR TARNISH    : Pigment producing bacteria formation of hard ,soft deposit on surface of restoration (eg-calculus) formation of thin film oxide and sulphide. CLASSIFICATION OF CORROSION CHEMICAL/DRY :  In chemical type of corrosion metal reacts to form oxide,sulphide  in the absence of  electrolyte for an example : oxidation of alloy particle in amalgam. 2) Electrochemical /wet corrosion: In electrochemical type of corrosion there will be formation of free electron ,electrolyte that provide pathway for transport of electrons. types of  electrochemical corrosion : A) galvanic corrosion B) concentration cell corrosion and C) stress corrosion  A) Galvanic corrosion:   When two dissimilar metal lie on direct contact with each other ,saliva acts
