(NV) - • Non-visible contamination (VC) - • Visible surface cleanliness NACE No. 5/SSPC-SP 12 - describes the use of a high-energy water stream to strip off existing coatings and remove contaminants on a substrate being prepared prior to coatings application. When compared to abrasive blasting, And water jetting - this method has certain advantages particularly for safety and environmental control. Respiratory protection requirements are less stringent and waste (abrasive) dispos...

NACE CIP Level 1 Sample Quizes with Certified Solutions All corrosion of iron at normal ambient conditions is an electrochemical process The cathode of a corrosion cell has an opposite electrical polarity to the anode Based on the galvanic series presented in the NACE CIP Level 1 Manual, which three can be used effectively as galvanic anodes for carbon steel? Zinc, aluminum, magnesium A corrosion inhibitor is a substance that, when added to an environment decreases the rate of corrosion A de...

Vulcanization is a physicochemical (physical and chemical) change resulting from the cross linking of the unsaturated hydrocarbon chain of natural rubber (polyisoprene) with sulfur, and the application of heat. Three factors that affect the properties of the vulcanizate (vulcanized product) - answerPercentage of sulphur and accelerator used Temperature of the curing process Time of cure Methods used to cure (vulcanize) rubber are - answerAutoclave (vulcanizer) cure Internal steam cure A...

Describe passivation - Passivation is the formation of a protective oxide Film on the surface reducing its chemical activity and its ability to corrode Describe the following factors and how they affect corrosion - Oxygen: oxygen increases the rate of corrosion temperature Temperature: corrosion usually accelerated with increasing temperature Chemical salts: increase the rate of corrosion by increasing the efficiency of the electrolyte humidity: the wetter the environment, the more corros...
