Description
Technical field
The present invention relates to a kind of device that the decay resistance of material is tested of being used for, be specifically related to a kind of high-temperature sulfidation attack experimental provision that is used for material.
Background technology
The high temperature vulcanized of metal material generally occurs in the equipment that uses mineral fuel and energy conversion, relates to modern industries such as aviation, petrochemical complex, thermal power generation, coal gasification.The high temperature vulcanized speed of metal is than fast many of its oxidation rate, and harmfulness is very big.
In order to study the high temperature vulcanized mechanism of metal, need in specific sulfuration experimental provision, measure the corrosion kinetics under high temperature sulphur atmosphere of metal.The high temperature sulphur environment of realizing in the experimental provision generally has two kinds, and a kind of is the volatilization of solid elemental sulfur, and it is 1～10 that may command sulphur is pressed
-2Atm, another kind adopt H
2S-H
2Atmosphere, may command sulphur is pressed wider range, is about 10
-2～10
-10Atm.H
2S-H
2The sulphur pressure ratio that atmosphere realizes is less, and the equipment that experiment needs is more, complicated operation; The attainable sulphur of the volatilization of solid sulfur is pressed higher, but then solidifies owing to the elemental sulfur chance is cold, and being easy to influences experimental result attached on the experimental provision.
Mostly be to adopt the volatilization of elemental sulfur to come designing apparatus both at home and abroad, its core component is exactly the quartz spring thermobalance.The characteristics of this equipment are exactly can the weightening finish of continuous coverage sample in corrosion process, and absolute precision is higher.But the equipment complexity, cost of manufacture is higher, and once can only measure a sample, can not realize the contrast of a plurality of samples under same environment, and especially relatively more responsive to vulcanization environment simple metal is as pure nickel etc.
Summary of the invention
Technical matters to be solved by this invention provides a kind of easy, and cost of manufacture is low, and is practical, the high-temperature sulfidation attack experimental provision that is used for material that can experimentize to a plurality of samples simultaneously.
In order to solve the problems of the technologies described above, the present invention is a kind of high-temperature sulfidation attack experimental provision that is used for material, have in the container of cover plate and be provided with support, described support is provided with the filament hook that is used to hang sample, the bottom of described container is placed with the simple substance sulphur of certain mass, described container is connected with one group of vacuum system and one group of argon gas gas charging system, one group of heating system is provided with the corresponding heating of filament hook that sample is hung in interior being used to of described container, and another group heating system is provided with the corresponding heating of simple substance sulphur that place the bottom of described container.
The top of described support is provided with thermofin.
Every group of described heating system is made of a temperature controller, a thermopair and a resistance furnace respectively, and described temperature controller connects a described thermopair, the described resistance furnace of the corresponding measurement of described thermopair.
Described container is a rustless steel container.Described support is a stainless steel stent.Described filament hook is the stainless steel filament hook.Described thermofin is the stainless steel thermofin.
Described argon gas gas charging system is made up of argon bottle and the bumping bag on the export pipeline that is located at described argon bottle.
Adopt the high-temperature sulfidation attack experimental provision that is used for material of technique scheme, have cover plate rustless steel container, two groups of resistance furnaces, thermopair and temperature controllers, have the vacuum system of argon bottle, in rustless steel container outside, one group of resistance furnace and thermopair are positioned at the place of stainless steel filament hook hook; Another group is positioned at container bottom.Every group of described heating system is made of temperature controller, thermopair and a resistance furnace respectively, one group is used to control the sulfidation corrosion temperature, one group of heating system is being controlled the temperature of sulphur, utilizes the saturated vapor pressure of sulphur and the relation of temperature to control the interior sulphur pressure of rustless steel container; Vacuum system comprises vacuum pump, pipeline, valve, is used for removing oxygen and nitrogen with the rustless steel container the inside before the corrosion.Argon bottle and bumping bag guarantee that the atmosphere in the preceding rustless steel container of corrosion is an about atmospheric argon gas.Be placed with thermofin on the support in the rustless steel container, be used for guaranteeing that corrosion temperature is constant on the one hand, be used for hanging sample on the other hand and stop that sulphur steam permeates upward.
In order to guarantee the sealing of container, the leather washer that scribbles vacuum grease is arranged between cover plate and container.
The present invention is specially at the high temperature vulcanized dynamic (dynamical) experimental provision of non-continuous, can realize same temperature, and it is high temperature vulcanized that different sulphur are depressed, and can realize that also same sulphur presses, high temperature vulcanized under the different temperatures.Can regulate being no more than 1000 ℃ corrosion temperature, control sulphur by the temperature of regulating simple substance sulphur and press, controlled sulphur pressure scope is 1～10
-2Atm.
The present invention is simple in structure, and is with low cost, easy to operate, can carry out under same corrosion environment a plurality of samples simultaneously high temperature vulcanized, the comparative height of experiment.After stopping heating,, can realize that sulphur steam solidifies recovery in the bottom, prevent it, improve the precision of experiment attached to sample surfaces by to rustless steel container bottom water-cooled.
