A generic term covering several processes applicable to steel that change the the chemical composition of the surface layer by absorption of carbon or nitrogen, or a mixture of the two, and, by diffusion, create a concentration gradient. Cast(1) A term indicating in the annealed state as ...
Nickel's other important ore minerals include pentlandite and a mixture of Ni-rich natural silicates known as garnierite. Major production sites include the Sudbury region in Canada (which is thought to be of meteoric origin), New Caledonia in the Pacific, and Norilsk in Russia. Nickel is ...
Destructive distillation is the strong heating of a substance in the absence of air. Pis processed in industries to get some useful products such as 'Q', 'R' and 'S. 'S' is obtained during the processing of P' to get 'Q, 'R' is a mixture of about 200 substances. Identify 'P'...
8). In Erdemir (a steel production plant in Turkey), approximately 125 kg BOF slag, 12.5 kg effluent slag, 18 kg slag remaining in the steel pot, and 15 kg desulphurization slag are formed during the processing of one-ton of hot molten steel and slag mixture (impurities). Sign in to ...
The steel coupons were polished with different grades of silicon carbide (400, 600, 800, 1000 and 1200), degreased in ethanol/acetone (30:70) mixture, repeatedly washed with anhydrous ethanol before drying with pure N2 (99.999% purity). Only epoxy-sealed coupons were utilized for the ...
