Research abstract
THE PROPOSED STUDY SEEKS TO ESTABLISH THE DIRECT RELATIONSHIP BETWEEN MELT POOL FLUID DYNAMICS AND MICROSTRUCTURAL CONTROL IN LASER SURFACE ALLOYING AND TO CONTRIBUTE TO THE OVERALL UNDERSTANDING AND CONTROL OF THE ALLOYING PROCESS. A UNIQUE MIXING MECHANISM HAS BEEN PROPOSED WHICH EXPLAINS PRESENT ANOMOLIES OBSERVED IN ALLOY MIXING BEHAVIOR DURING LASER HEATING. A COMBINED THEORETICAL-EXPERIMENTAL EFFORT IS PROPOSED TO STUDY THE THERMAL AND COMPOSITIONAL CONTRIBUTIONS TO MARANGONI-TYPE FLOW IN THE ALLOY MELT POOL. BY UNDERSTANDING THE FLOW CHARACTERISTICS AND MIXING MECHANISMS IN THE LASER MELT POOL, CONSIDERABLE CONTROL OVER THE ALLOYING PROCESS IS ACHIEVED AND PRESENT COMMERCIAL APPLICATIONS OF THIS PROCESS ARE EXTENDED WELL BEYOND CURRENT CAPABILITIES.
