摘要： PURPOSE:To allow all grains to adhere, in a state having molten parts around them, to the surface to be thermally sprayed at the time of explosion thermal spraying, by adding and binding a low-m.p. fine-grain oxide to stabilized zirconia. CONSTITUTION:A fine-grain oxide having a m.p. lower than that of stabilized zirconia is added and bound to stabilized zirconia. It is desirable that fine-grain oxide is a mixture of one or more kinds among alumina, silica, and titania each having a grain size smaller than that of stabilized zirconia. Moreover, the amount of the fine-grain oxide to be added is regulated to about 1-10wt.% based on the thermal spraying material after addition and the fine-grain oxide is bound to the stabilized zirconia by means of sintering, etc. When this thermal spraying material is thermally sprayed by an explosion thermal spraying method, the thermal spraying material reaches the surface to be thermally sprayed in a molten state or at least in a state where the fine-grain oxide is melted so that it covers the stabilized zirconia. Accordingly, a thermally sprayed film having high cross-sectional hardness and reduced in cross-sectional porosity can be formed.

摘要： PURPOSE:To increase the number of I complex ion, as an oxidizer, exponentially as a counterpart reaction substance is dissolved in a solution and to carry out oxidation reaction acceleratedly by using an interhalogen compound such as I complex ion as an oxidizer. CONSTITUTION:A reaction substance 2 is oxidized by an I complex ion solution 1 containing interhalogen complex ions which work as an oxidizer and a part of the substance is dissolved in the I complex ion solution 1. Subsequently to this, the I complex ion 3 working as an oxidizer is reduced to 3 mole I ion and the I ion reacts with iodine 4 existing in the I complex ion solution 1 to newly produce 3 mole I comple ion 3 and thus the I complex ion 3 as an oxidizer in the I complex ion solution 1 increases with time. When the I complex ion 3 which works as an oxidizer increases, the reaction substance 2 is oxidized and the amount of corrosion or breaking (dissolution) of the substance 2 is increased and consequently the amount of breaking the reaction substance 2 together with the amount of the I complex ion 3 is increased exponentially.

摘要： PURPOSE:To control the extent of the damage of corrosion by detecting the extents of corrosion damages, cumulative corrosion decreases, and hole corrosion depths in various corrosion states in gas liquid environment including a varying halogen element. CONSTITUTION:A halogen molecule concentration arithmetic part 2 calculates halogen molecule concentration in liquid phase by using halogen molecule concentration and temperature which are detected 1. Those data are used to obtain material characteristic data, environment data, and various corrosion state generation data, and halogen complex ion concentration is calculated 6. Various corrosion mode generation data are used for the permissible value of an arithmetic part 7 to calculate the permissible time ta of various corrosion modes corresponding to the halogen complex ion concentration obtained by an arithmetic part 6 and the calculated data is used as the corrosion damage data. A corrosion damage arithmetic part 8 calculates corrosion damage extents DELTAphi=deltat/t corresponding to the generation of various corrosion modes from a one-measurement time DELTAt and the permissible time ta at the time (t) and also finds a corrosion damage extent phi(t)=phi+DELTAphi up to the time (t) and phi for the total operation time. Those phi are compared with permissible quantity and decided 9.
