Influence Of Temperature On

Abstract Temperature is considered a complicated external factor of the susceptibility of stainless steels to the pitting. This paper deals with the corrosion behaviour of AISI 316Ti stainless steel in temperature range 22 - 80°C in aggressive chloride environments (3 and 5% FeCl3 solutions). The corrosion resistance of tested steel is evaluated on the base of results of exposure immersion tests and cyclic potentiodynamic tests. According to the obtained results the resistance of AISI 316Ti to the pitting is markedly affected by temperature changes in the range 22 – 80°C. Intensity of corrosion attack increases with the rise of Cl− concentration. Gentle changes of temperature and Cl− concentration cause significant differences in character of local damage. The appearance of pitted surfaces changes with the rise of the temperature (a density of pitting increases, a size of pits decreases). The strongest change in appearance is observed between 40 and 50ºC.

Cr Coating

It is considered that Ti-Cr coatings can improve strength, hardness, wear resistance and corrosion resistance of base control alloys as these coatings combine the advantages of both Ti coating and Cr coating. In this study, the Ti-Cr coatings were deposited by diffusion method. The effects of deposition temperatures on the compositions and microstructures of the Ti-Cr coatings on 45# carbon steel were investigated. The coatings formed consisted of three layers. The outer layer contained Ti and Cr carbides beneath which a diffusion layer was developed. The inner layer was enriched in Ti and Cr. At low temperature (800°C) the outer layer of Ti-Cr coatings was dominated by TiC. Increasing deposition temperature led to the enhanced diffusion of Cr and a Cr7C3 and Cr23C6-dominated outer layer was identified. The growth process of Ti-Cr coating was analyzed and simulated.

Atomic Form Factor

Temperature affects both elastic and inelastic scattering of electrons in a crystal. The Debye-Waller factor, B, describes the influence of temperature on the elastic scattering of electrons, whereas the imaginary part of the (complex) atomic form factor, fc = fr + ifi, describes the influence of temperature on the inelastic scattering of electrons (i.e. absorption). In HRTEM simulations, two possible ways to include absorption are: (i) an approximate method in which absorption is described by a phenomenological constant, μ, i.e. fi; - μfr, with the real part of the atomic form factor, fr, obtained from Hartree-Fock calculations, (ii) a more accurate method in which the absorptive components, fi of the atomic form factor are explicitly calculated. In this contribution, the inclusion of both the Debye-Waller factor and absorption on HRTEM images of a (Oll)-oriented GaAs crystal are presented (using the EMS software.Fig. 1 shows the the amplitudes and phases of the dominant 111 beams as a function of the specimen thickness, t, for the cases when μ = 0 (i.e. no absorption, solid line) and μ = 0.1 (with absorption, dashed line).
