Description
Technical field
The present invention relates to welding processing technical field, specifically surfacing cobalt-chromium-tungsten alloy powder and its application method.
Background technology
Spiral propeller, mounted in the accelerator of wheel quarter.In use for some time, mill occurs in spiral propeller
Damage, have influence on the normal of steamer and give it the gun, the service life for also resulting in spiral propeller drastically shortens.If more being renewed
Spiral propeller, cost is higher.
And for example pump leaf valve seat, bearing, no, it is necessary to timely be changed when producing a certain degree of abrasion when deployed
Then influence whether that normal install positions and motion transmission, but changing the cost that equipment can be caused to use again increases.
Three of the above part, according to replacing, the part after abrasion can be dropped, cause along the wasting of resources, urgently
Need it is a kind of the part of above-mentioned abrasion can be subjected to repairing sizes, so as to realize the material of recycling.
The content of the invention
In order to solve deficiency of the prior art, the present invention proposes surfacing cobalt-chromium-tungsten alloy powder and its application method.
The technical problems to be solved by the invention are realized using following technical scheme：
Surfacing cobalt-chromium-tungsten alloy powder, includes the component of following mass percent：
C is that 3~4%, Cr is that 35~45%, Si is that 0.5~0.9%, W is that 15~17%, Fe is that 0.1~0.5%, Mn is
1~2%, Mo is that 1~2%, Ni is that 4~5%, surplus is Co.
The surfacing application method of cobalt-chromium-tungsten alloy powder, methods described step is as follows：
The first step：Workpiece surface processing；
Second step：The inspection of cobalt-chromium-tungsten alloy powder：Moisture absorption phenomenon or storage period are checked whether there is whether more than 3 months；
3rd step：Drying process：Cobalt-chromium-tungsten alloy powder is incubated 2 hours in 150 DEG C of container；
4th step：Cobalt-chromium-tungsten alloy powder heap is welded in by workpiece surface using plasma arc powder surfacing equipment.
The beneficial effects of the invention are as follows：The invention belongs to face-centered cubic solid solution alloy, carbon and W content are high in alloy, make
The wear-resisting material abrasion characteristic of alloy is significantly improved.With premium properties such as heat-resisting, anti-corrosion, high red hardness.Impact strength is poor, heap
Tearing tendency is sensitive during weldering.Heap is welded in behind the surface of abrasion workpiece, it is possible to achieve the reparation to abrading section, realizes abrasion
The recycling of workpiece；The present invention can also the new workpiece surface of built-up welding, so as to play a part of pre- protection.
