The method to determine thermal fields considering dependence of thermophysical and mechanical properties of coating materials and a base from the temperature, the running of plastic deformations and stresses relaxation at plasma spraying is suggested.
The mathematical model of calculation of thermal field with moving boundary considering nonlinear feature of coating growth at layer-by-layer deposition and dependences from thermophysical properties of materials of the system «coating-base» is developed.
At the materials interface connections there is an ideal thermal contact, i.e. the fourth class boundary condition is performed [9, 10] (5) The formulated nonlinear problem is solved by numerical methods of finite differences [11, 12].
In this case, the boundary points can be external and then they meet the boundary conditions of the II-th or III-th kind, or internal points [14, 15], that is, to be an interface between two materials and then they meet the boundary conditions of the IV-th kind.

Through bridging and aggregation function, cadmium ions can be removed while cloud materials can be reduced.
Fig. 8 shows that PHA is more effective in the removal of the cloud materials and Cd2+.
The removal rate of Cd2+ rises to some extent, while the removal rate of the cloud materials can rise to over 90%.Those evidences indicates that the cloud materials and Cd2+ can co-exist as well as enhance the removal.
(4) Co-existed with the cloud materials, PHA’s ability to remove Cd2+and the removal rate of the cloud materials can rise too
