Plasma spray can be used to produce coatings. of virtually any metallic, cermet, or ceramic ma-. terial. The coatings are used for most of the types. of applications described in a subsequent section. The transferred plasma-arc process adds to. plasma spray the capability of substrate surface heat-. ing and melting. Figure 7 is a schematic repre-. sentation of the process.
Blood plasma is prepared by spinning a tube of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is then poured or drawn off.Blood plasma has a density of approximately 1025 kg/m 3, or 1.025 g/ml.he use of blood plasma as a substitute for whole blood and for transfusion purposes was proposed in March 1918, in the correspondence columns of the British Medical Journal, by Gordon R. Ward. Dried plasmas in powder or strips of material format were developed and first used in World War II.
