Specimens prepared by other, less widely used techniques, such as ion sputtering, flash evaporization, gas atomization, chemical reduction, electrodeposition, and laser surface melting-self-quenching, have also been studied as catalysts. [Pg.331]

The demands of practical applications led to attempts to overcome the high electric resistance of thin ribbons by a new technical solution of laser-induced surface vitrification (105, 106). First an amorphous alloy ribbon was adhered uniformly to a nickel plate by heat treatment. Subsequently, this surface alloy layer was transformed to the amorphous structure by laser surface melting and self-quenching (107). A sample consisting of Pd56Rh23P oSi9 adhered to bulk crystalline nickel exhibited anodic characteristics very similar to those of the melt-spun amorphous ribbon (102). Clearly, similar improvements forced by practical demands will be a part of the future use of amorphous alloys. [Pg.342]

The laser surface melting can be combined with a simultaneous controlled addition of alloying elements. These alloying elements diffuse rapidly into the melt pool, and the desired depth of alloying can be obtained in a short period of time. By this means, a desired alloy chemistry and microstructure can be generated on the sample surface and the degree of microstructural refinement will depend on the sohdification rate. The smfaoe of a low-cost alloy, such as low carbon steels, can be selectively alloyed to enhance properties, such as resistance to wear and corrosion (Davis, 2001). [Pg.309]

The technique of laser surface melting (LSM) is well known and has been in use for many years for modifying the surfaces of both ferrous and non-ferrous substrates (Liu et al., 2006). LSM of the engineering alloys, in general, is aimed at improving the corrosion resistance by modifying the... [Pg.250]
