Anticorrosion Treatment
It is important to block the porosity of nickel with a suitable anticorrosion treatment based on the application of a sealant to inhibit aggressive agents from contact with the base metal through the pores.
These anticorrosion sealants, unlike the antifriction ones, are petroleum based and have a viscosity that varies according to the type of sealant, concentration and processing temperature.
In general, the different types of sealants used for anticorrosion treatments are divided intoR68, R80, R100 and Q100, used according to the environment with which the metal will be in contact. Following are the applications of the different types:
