1.导言以磨损和腐蚀形式出现的损耗,使世界经济每年损失高达800亿西德马克左右。在西德仅仅除锈一项就须耗费全年型钢产量的三分之一,约40～50亿西德马克。在这些数字中,几乎还不包括因磨损件失去功能而造成的损伤,这种损伤远远超过本 1. Introduction Losses in the form of wear and corrosion have cost the world economy up to about S $ 80 billion annually. Only a derusting in West Germany will have to spend one-third of the annual steel production, about 40 to 5 billion West Germany mark.
