INTRODUCTION
In dental restorative technique is used materials with a range of biological, biomechanical and bio security characteristics [2,3,8].
MATERIALS&METHODS There were used 4 types of CoCrMo alloys to achieve 50 RPD frameworks: Alloy “C” (Vaskut Kohàszati Kft –, Budapest, Hungary), Heraenium CE (Heraeus Kulzer, Senden, Germany), Wironit (Bego - Bremen, Germany), Wironit Extrahard (Bego - Bremen, Germany).
After deflasking, the extraction procedure of RPD metallic framework from the mold, follows Sandblasting – the procedure that removes dental investment material, then the oxides are removed, after which the alloy surface is conditioned.
In case of grinding, the metallic material surface becomes covered by some rough parallel treads.

Abstract: Permeation length, permeation coefficient of water permeated into concrete and chloride
ion diffusion coefficient of C30, C45 and C60 concrete were studied by high hydraulic method
(0.5MPa~25MPa) and quick method of testing chloride ion diffusion respectively, and relationship
of concrete permeability tested by two methods was analyzed too.
Materials and test methods 2.1 Materials and mix proportions Chinese standard 32.5 and 42.5 ordinary Portland cement, river sand with fineness modulus of 2.69 and apparent density of 2610kg/m3, crushed basalt stone with maximum size of 10mm and apparent density of 2810kg/m3 and fly ash, SJ-2 air-entraining agent and UNF-5 water-reducing agent were used.

It is determined by the heat and mass transfer peculiarities in the heated layer and on the surface of these fuel materials during the local thermal effect.
The phase transfer heat means that the evaporation of any liquid fuel is essentially higher (more than in 10 times) than the heat, spent for gasification of the forest fuel materials (the thermal decomposition).
