            material inputs such as coatings, corrosion inhibitors, corrosion-resistant materials;
            (ii) changes in capital equipment; and (iii) changes in technical services.
              The breakdown of industry indicators into its components is shown in Figure 2.1
            for industrial chemicals and public utility sectors.

              Inputs. These include the costs of coatings and plating for corrosion control,
                 corrosion inhibitors, maintenance and repair, corrosion-resistant metals, and
                 cathodic protection.
              Capital Replacement. Replacement of capital equipment and associated facilities
                 in industry is affected by corrosion.
              Growth Capital. The costs of capital equipment are affected by corrosion through
                 replacement lives of capital equipment.
              Value Added. Activity of industry is affected by corrosion through inputs such as
                 costs of research and development and technical services. When the coefficients
                 (industry indicators) in the IO matrix are modified to reflect the absence of
                 corrosion, the IO matrix can be used to indicate the inputs needed to produce
