Materials coatings for valves: coal-liquefaction components and instrumentation. Quarterly report, October 1-December 31, 1981
This quarterly report summarizes activities in the development of erosion resistant coatings for the wear prone parts of letdown and control valves used in coal conversion process plants. The objective of this program is to demonstrate material and coating process concepts developed previously at SNLA and to effect technology transfer to industrial applications. The tasks to be performed are: (1) determine the applicability of existing materials and material processes to industrial valve materials and configurations; (2) produce sets of valve trim for initial evaluations in pilot plant operations; and (3) develop such coating materials and processes to achieve task 2 or that will result in improved materials. In preliminary evaluations, the ability to directly apply TiB/sub 2/ coatings on K701 (WC) cermets by CVD was demonstrated. Efforts to achieve this on other commercial substrates of interest such as K703 have not produced consistent results. Hence, the substrate material favored for the first generation pilot plant prototype is K701.
