Description
Technical field
The invention belongs to workbench technical field, more particularly to a kind of plasma cladding multifunctional workstation.
Background technology
In agricultural production, the abrasion of agricultural tool is mainly impact wear, abrasive wear and corrosive wear, wherein touching
The wear form generated in component and soil contact process in native component operation process is mainly abrasive wear, accounts for soil-engaging component mistake
More than 80% effect totality.The most popular agricultural machinery soil-engaging component material in China is 65Mn at present, and the material wear ability is general,
Agricultural tool can not be met for a long time, the job requirements of high intensity.Once wearing it is necessary to integral replacing, this is resulted in component
The significant wastage of material.
Therefore, agricultural tool soil-engaging component wear problem is solved, is the task of top priority of current China's agricultural production.Utilize height
Beam melting and coating technique applies the material that last layer is cheap, wearability is good on agricultural soil-engaging component surface, is to solve the problems, such as this
A kind of effective ways.High energy beam cladding is to use high energy beam (laser beam, ion beam etc.) as moving heat source, cheap, resistance to
The excellent metal material powder cladding of burn into wear-resisting property increases the wearability of the workpiece surface with this to workpiece surface.When
Preceding melting and coating technique mainly includes laser melting and coating technique, plasma melting coating technique etc., wherein the research in terms of laser melting coating more into
Ripe, but it compared with plasma cladding, capacity usage ratio is low, device fabrication is high with maintenance cost, and have to working environment it is special
It is required that.And although plasma cladding dimensional accuracy and drip molding quality are slightly less than laser melting coating, equipment cost is only the latter's
1/5, production efficiency, powder using efficiency, capacity usage ratio etc. are higher by laser melting coating several times.Agricultural tool is to surface fused coating ruler
Very little required precision is not high, therefore plasma melting coating technique may be used to enhance the wearability on its surface.
Plasma cladding is using plasma arc as heat source, by the alloy powder introduced by dust feeder and parent metal table
Layer melts simultaneously, and later with the transfer of plasma arc, quick solidification occurs for fusing metal, and being formed has the property such as wear-resisting, corrosion-resistant
The cladding layer of energy.Since the heat of plasma melting coating technique is concentrated, action time is short, so cladding area heat affecting is small, stress is small；
And cladding layer is metallurgical binding with matrix, and bonding strength is high, and coating structure is uniformly tiny, has good comprehensive performance.
During existing actual tests, it is found that workpiece surface temperature has larger impact to plasma cladding effect.
In initial experiment, since workpiece temperature is relatively low, part metals powder is caused to fail to melt, is attached to clad layer surface, influence to melt
Coating quality；And with the continuous progress of experiment, since cladding layer metal heat is constantly accumulated, on workpiece bulk temperature is continuous
The problems such as rising, the setting rate of fusing metal made to reduce, cause clad layer surface uneven.
