Description
Technical field
The present invention relates to field of material technology, more particularly to a kind of abrasion resistant materials for producing flow passage component of slurry pump.
Background technology
Toughness material being used centrifugal type slurry pump abrasive wear and corrosivity abrasion centrifugal type slurry pump flow passage components more, its
The synergic wear that flow dynamics abrasive wear is made up of micro-ploughing and formation abrasion.Centrifugal type slurry pump runs well
During, the fluidised form flowed through in the liquid latrine two-phase slurry of flow passage components is turbulent condition, solid particle (coal, spoil, magnetic in slurry
Iron Ore Powder) shape be in random orientation.
With the solid particle on low-angle impact flow passage components surface, when being contacted with surface with wedge angle, in contact point very little
The vertical component of surge very high, surge will be produced on area makes solid particle press people's material surface, surge
Horizontal component make its along be roughly parallel to flow passage components surface direction move, make material surface contact point produce horizontal plastic property
Deformation, so as to cut out a certain amount of micro-volume material, causes the micro-ploughing of flow passage components.
With the solid particle on high attack angle impact flow passage components surface in the case where the vertical component of surge is acted on, make solid
Grain pressure people material surface forms elastic-plastic deformation, to particle stops press-in motion, ultimately forms irreclaimable plasticity and becomes
Shape-impact dent, has the material stacking thing of plastic deformation extrusion in pit edge.Impact pit edge deposit will be squeezed again
Deform and shift and peeled off from material surface, cause a certain amount of micro-volume material to lose, cause the formation abrasion of flow passage components.
In fact, in slurry often there is micro-ploughing with deformation mill in abrasion of the solid particle to flow passage components surface simultaneously
Damage.Wear extent is two kinds of compound action results of abrasion.During low incidence, based on micro-ploughing, supplemented by formation abrasion；Favourable opposition
During angle, based on formation abrasion, supplemented by micro-ploughing；35—40.During the angle of attack, synergic wear amount reaches maximum.
When the surge level of solid particle in slurry (depends on hardness, shape, the angle of attack, impact velocity, the mistake of particle
Stream unit material surface hardness etc.) it is smaller when, particle can not press people's material surface, directly produce plastic deformation or Plastic Flow,
But substantial amounts of solid particle repetitive impact over time, will also result in the fatigue flake of material, i.e. fatigue wear.
Therefore, those skilled in the art are devoted to reducing always the fretting corrosion defect of Pulp pump.
The content of the invention
It is an object of the invention to propose a kind of abrasion resistant materials for producing flow passage component of slurry pump, the material is prepared into
The flow passage component of slurry pump decay resistance for arriving is outstanding.
It is that, up to this purpose, the present invention uses following technical scheme：
A kind of abrasion resistant materials for producing flow passage component of slurry pump, it is characterised in that the material is wrapped by weight percent
