ELECTROCHEMICAL BEHAVIOUR OF Al-BRASS IN SEAWATER
Corrosion of the Al-brass in 3.5 % NaCl solution and natural seawater was investigated with potentiodynamic polarization technique. Corrosion rate obtained in natural seawater was higher than in 3.56 % NaCl solution. The metallographic examinations indicated the occurrence of pitting corrosion in both cases.
Impingement Corrosion of Condenser Tubes
AbstractThe problems of impingement corrosion of condenser tube materials are reviewed, with special reference to the power industry of the UK. The South Eastern Region of the Central Electricity Generating Board has set up a laboratory to study the corrosion behaviour inflowing sea water of metals used in power station cooling water systems. The jet impingement facilities of the laboratory are described and the results of recent work presented. These include the impingement characteristics of some standard condenser tube materials, the modification of these characteristics by such methods as cathodic protection and ferrous sulphate dosing of the sea water, and the resistance to impingement corrosion of some new materials. Particular attention is paid to titanium and its resistance to this form of corrosion.
Study on workspace analysis and simulation of 6-DOF painting robot based on monte-carlo method
Comparing recent kinds of methods working on robot workspace when we design to calculate the workspace of 6R painting robot,we bring Monte-Carlo method to analysis the workspace according to the actual working condition. With robot Tool Center Point(TCP) position aggregate via the solution of forward kinetic equation,Monte-Carlo method analysis and simulate painting robot workspace efficiently.
