Question

A carburizing process is carried out on a 0.30% carbon steel by introducing 1.0% C at the surface at 970°C for an hour. The following data represent the concentration profile for this process.

Transcribed Image Text:Table 2: Concentration profile from carburizing process Jadual 2: Profil kepekatan daripada proses penyusukkarbonan Distance of Diffusion from surface, x (mm)/Jarak resepan daripada permukaan x (mm) Concentration of Carbon, Cx(wt%C)/Kepekatan karbon Cx (wt%C) 0. 0.2 0.10 0.4 0.24 0.6 0.27 1.0 0.29 (i). State the purpose of carburizing process for steel. Nyatakan tujuan proses penyusukkarbonan dilakukan terhadap keluli (ii). Plot the concentration profile (concentration vs. distance) of the carbon within 1 mm of the surface. Plot profil kepekatan (kepekatan melawan jarak) bagi karbon untuk jarak 1 mm dari permukaan keluli (iii). From the plot, is it possible to determine the rate of diffusion for this process? Explain. Dari plot terhasil, adakah kemungkinan kadar resapan bagi proses ini dapat ditentukan. Terangkan.
