This publication outlines the various types of corrosion and how they affect the metals and alloys used in marine engineering. It discusses methods of corrosion protection and examines how system design can best avoid the potential for corrosion. It also looks at specific environmental corrosion in boilers, gas turbines and fresh water cooling systems.
Onboard corrosion can take various forms, leading to malfunction, downtime and expensive repair.
This publication describes the mechanism of different types of corrosion, including electrochemical and mechanically assisted corrosion. This is followed by a detailed analysis of metals and alloys, including guidance on where they may be found on board, their vulnerability to corrosion and suitable protection systems. The various protection systems and their application are examined, including painting, cathodic protection, chemical treatments and metal coatings.
The book also looks at practical design considerations that can help reduce corrosion, focusing on structural systems, and designs to avoid cavitation erosion and impingement corrosion.
