Materials Degradation and Its Control by Surface Engineering


Book Description

This book provides a general holistic view of materials degradation without undue emphasis on aqueous corrosion with the neglect of other important topics such as liquid metal corrosion. Discussion of materials degradation is balanced by detailed description and evaluation of surface engineering as a means of managing materials degradation. Thus, the trainee engineer is presented with a comprehensive view of the problem rather than just a part of the problem. The control or management of materials degradation is not only discussed in scientific terms, but the economics or financial aspects of materials degradation and surface engineering is also discussed in detail with the help of analytical models.

Book Description

This document specifies the requirements for treated zinc electroplated coatings on steel, including the information to be provided by the purchaser to the supplier and the requirements for heat treatment before and after electroplating. This document does not specify the surface condition of the base metal before zinc electroplating, but defects on the base metal surface will have an adverse effect on the appearance and performance of the coating. This document applies to treated zinc electroplated coatings on iron or steel. This document does not apply to: -- zinc electroplated coatings on unformed steel sheets, strips and wires; -- zinc electroplated coatings for tightly wound springs; -- zinc electroplated coatings for non-protective decorative purposes. The thickness of the electroplating coating on threaded parts can be limited by thread grade or assembly size requirements.
