Abstract
The invention discloses a cylindrical device for improving an ion nitriding effect. The cylindrical device is named as a porous assisted nitriding cylinder. The height of the cylinder is about 200cm, the internal diameter of the cylinder is about 45mm, the external diameter of the cylinder is about 75mm, a certain number of through holes with the diameters of smaller than 10mm are formed in the cylinder, and the density and arrangement conditions of the holes are determined according to actual demands. When being used for ion nitriding, the cylindrical device is placed on a cathode disc of an ion nitriding furnace; and relatively-high temperature is generated in the holes in the device by virtue of a hollow cathode effect of ion nitriding. The device can be filled with a catalyst, a compound, metals and other substances. By using the device, the uniformity of the furnace temperature can be improved, and the efficiency of the catalyst can be increased.
Description
Technical field
The present invention relates to technical field of heat treatment, especially a kind of device improving ion nitriding effect.
Background technology
Ionitriding is as a kind of Surface thermo-chemical treatment, and it not only can improve workpiece surface hardness and surface property, the more important thing is that the distortion of the workpiece after ion nitriding is minimum, need not reprocess.In addition, ion nitriding is pollution-free in addition, consumes energy low, is easy to the advantages such as control.So the application of ion nitriding technology constantly expands.But the shortcomings such as the time of ion nitriding is long, nitriding depth is thin govern its development.Although a lot of scientific worker, in order to improve alloying layer thickness and shorten nitriding time, also takes a lot of method.As: adopt catalyzer, carry out workpiece surface shot-peening, adopt temperature cycling technique etc.But these methods have certain limitation, poor effect, and actual application value is lower.
When using catalyzer to carry out ion nitriding, the temperature due to ion nitriding is lower and the mode difference of stove put into by catalyzer, thus makes the DeGrain of catalyzer.
Summary of the invention
The object of the invention is to improve ionitriding effect, improve the effect of catalyzer in ionitriding process, change the mode etc. of tufftride.
The invention provides a kind of device, this device is round shape, and material is can electro-conductive material.The body of cylinder has the aperture of some amount, aperture is through hole, and its diameter is all less than 10mm.About cylinder heights 200cm and internal diameter about 45mm, external diameter about 75mm, the both ends open of cylinder or one end open one end are closed.
When this device uses, can keep flat, vertically place, also can hang placement, best modes of emplacement is vertical placement.No matter which kind of modes of emplacement, this device all must be connected with negative electrode.
Owing to have employed technique scheme, the present invention has following beneficial effect compared with modern technologies: (1) the present invention utilizes hollow cathode effect, makes cylindrical wall temperature higher than surrounding environment, as boosting thermal source, thus can improve furnace temperature; (2) inside of this device can catalyst filling, metal and the material such as nonmetal.Because the temperature of this device is higher, the volatilization of its inner material can be accelerated, thus improve the effect of ion nitriding; (3) material of carbon containing is loaded onto in this device inside, thus changes the mode of tufftride, tufftride is simplified and reduces the cost of tufftride; (4) utilization of the present invention can speeding-up ion nitriding process.

Embodiment
As shown in Figure 1, this device is vertically placed on cathode disc, and keeps suitable distance with other workpiece.Ready catalyzer or other desired material are put into cylinder (material put into will be tried one's best drying, pure, preferably particle dress, and the amount put into is that 1/3 of cylinder heights is advisable).Then, cover body of heater and be evacuated down to about 50pa, starting power supply, beating arc, intensification, logical ammonia.After arriving determined temperature, turn off pulse two hours, and then open pulse, after about two hours, then turn off pulse.Circulation like this.
