Cathodic and Anodic Protection–The cost of cathodic and anodic protection of metallic
structures subject to corrosion can be divided into the cost of materials and
the cost of installation and operation.Industry data showed that the 1998
sales of hardware components totaled $146 million.The largest share of the
cathodic protection market is taken up by sacrificial anodes at $60 million,of
which magnesium has the greatest market share.Major markets for sacrificial
anodes are the water heater market and the underground storage tank market.The
cost of installation of the various cathodic protection components for
underground structures varies significantly,depending on the location and the
specific details of the construction.For 1998,the average total cost for
installing cathodic protection systems was estimated at $0.98 billion (range:
$0.73 billion to $1.22 billion).The total cost for replacing sacrificial anodes
in water heaters and corrosion-related replacement of water heaters was
estimated at $1.24 billion per year.Therefore,the total estimated cost forcathodic and anodic protection is $2.22 billion per year.

阴极和阳极的保护-保护易受腐蚀的阴极和阳极金属结构的成本可以分为材料成本和安装操作成本两部分.产业数据显示,1998年硬件组件的销售额总计1.46亿元.阴极防腐蚀保护的最大的市场份额被牺牲阳极占去,达到6000万元,其中,镁具有最高的市场占有率.牺牲阳极的主要市场是热水器市场和地下贮槽市场.不同的地下贮槽阴极保护组件的安装成本是明显不同的.这取决于建筑的位置和具体细节.1998年安装阴极保护系统的平均成本大约是9800万（7300万-1.2亿之间）.更换热水器牺牲阳极和置换腐蚀的热水器的成本大约每年1.24亿.因此,阴极和阳极保护的总预估成本是每年2.22亿元.
