Abstract:

The Technology Transfer program assists in the utilization and integration of the laser facility in the manufacturing of naval ordnance components and systems. This assistance consists of targeting workpieces and production steps suitable for laser processing in terms of cost effectiveness and quality enhancement, the development of techniques and procedures for such processing and the establishment of processing parameters and other pertinent data. The work is related to laser surface transformation hardening of steels. The response of a number of frequently used steels to such laser processing has been determined over a wide range of processing parameters, models, and calculator programs for the prediction of laser hardening have been developed and tested, and the necessary thermo physical constants of the various materials determined by statistical and empirical means. In addition to the transformation hardening survey, process development work relating to the laser hardfacing of aircraft carrier catapult rails have been performed, and preliminary techniques and processing data established for different combinations of hardfacing alloyssubstrate materials.
