Hot corrosion behavior of boiler tube materials in refuse incineration environment

摘要: Abstract Thermal spraying has emerged as an important tool of increasingly sophisticated surface engineering technology. The different functions the coating, such wear and corrosion resistance, thermal or electrical insulation can be achieved using coating techniques materials. purpose a hot resistant is to serve effective solid-state diffusion barrier between oxygen (or other gaseous) base metal. 50%Ni–50%Cr alloy produced by detonation spray method exhibited most resistance in laboratory test. This paper presents test results coated boiler tubes at actual refuse incineration plant. plant had operated for about 7 years without any problems are expected have longer life.
