The boundary reflection matrices for nonsimply laced affine Toda field theories defined on a half line with the Neumann boundary condition are investigated. The boundary reflection matrices for some pairs of the models are evaluated up to one loop order by perturbation theory. Then the exact boundary reflection matrices which are consistent with the one loop result are found under the assumption of ''duality'' and tested against algebraic consistency such as the boundary bootstrap equation and boundary crossing-unitarity relation.
We present explicit verification of the conjectured "duality" between D?' and G:" affine Toda theories up to f l order. We construct the exact S matrices for Da' and compare the residue of the simple pole of the S matrix with standard perturbation theory, using a 13-dependent renormalized mass.
In this investigation, tool grade P20 WC was coated using the Chemical Vapor Deposition (CVD) method. The specimen was coated uniformly with Al2O3 of 1.5 µm thickness over an additional coating of TiC. TiC coating thickness varied at four different thicknesses: 3 µm, 6 µm, 9 µm, and 12 µm. The investigation was conducted with a turning operation in high-strength steel at higher cutting speed. Using SEM and X-ray, the progress of crater wear was carefully observed.
