Description
Technical field
It the utility model is related to a kind of alloy screw, and in particular to covered with two layers of nickel chromium triangle on a kind of body of rod and thread surface
Alloy and almag composite powder coatings and a kind of alloy of the wear resistant corrosion resistant high temperature resistance and high strength of nickel-base alloy sawtooth
Screw rod.
Background technology
The conventional nut stem material in China has No. 45 steel, 40Cr, ammonification steel, 38CrMOAl, high temperature alloy etc., existing skill at present
The screw rod manufacture method of art is more using re-plating hard chrome after nitridation.Screw rod is often in high temperature, certain burn into strong wear, big
Being worked under moment of torsion, screw rod serious wear and not corrosion-resistant during due to work, its life-span is shorter, typically only some months, and
And the quality of product can be influenceed in the course of work, unstable product quality is often resulted in, yield rate is relatively low, thus serious waste provides
Source, its production cost remain high.
The content of the invention
The purpose of this utility model is to provide a kind of alloy screw, for prior art screw rod above shortcomings, carries
For a kind of composite powder coatings and nickel-base alloy sawtooth with wear resistant corrosion resistant high temperature resistance and high strength, there is well resistance to
Mill, corrosion-resistant, high temperature resistant, high intensity and it is unlikely to deform, good operating stability, a kind of alloy screw lasted a long time.
Used technical scheme is the utility model to achieve the above object：
A kind of alloy screw, including head, thread, connector, pole cap, the body of rod, nichrome coating, almag coating
With nickel-base alloy sawtooth, on the surface of the screw rod body of rod and thread, applied covered with two layers of nichrome coating and almag
Layer composite powder coatings, the alloy powder of the nichrome and almag composite powder coatings is formed, include 70-80% nickel
Chromium alloy powder, and 20-30% al-mg alloy powders, the powder size are 200-400 mesh, and the coating is in overall uniform, thickness
On the surface for as one man covering the screw body and thread, its thickness is 0.35mm；Secondly one layer is also covered with outer surface
Nickel-base alloy sawtooth, composition are Co-based alloy powder, and powder size is 300-400 mesh.
A kind of basic material of alloy screw uses 38CrMoA1, and quenched through HRC26-28.It is of the present utility model to add
Work process is：The processing of base material screw rod-->Screw surface sandblasting roughening treatment-->Subsonic speed oxy-acetylene spray gun spraying alloy is answered
Close powder to surface-->Be warming up to 1080 DEG C of remeltings make coating to metallurgical binding-->Rough polishing diamond lap polishing-->
Finishing polish and alloy powder cylindrical lapping to sawtooth-->Finished product assembles.
The utility model has the advantages that：Due to the utility model the body of rod and thread surface covered with two layers of nichrome with
Almag composite powder coatings and nickel-base alloy sawtooth, make screw rod possess good wear-resisting, corrosion-resistant and high temperature resistant and
High-intensity performance, and greatly add the active area of screw rod, be unlikely to deform, good operating stability, the work for extending screw rod
Make the life-span, improve finished product rate, resource can be greatlyd save, reduce cost.

The alloy powder of golden composite powder coatings, include 70-80% nichrome powder, and 20-30% al-mg alloy powders, the powder
Granularity is 200-400 mesh, and it is in that entirety uniformly, consistency of thickness is covered on the surface of the screw body and thread that the coating, which is,
Its thickness is 0.35 mm；One layer of nickel-base alloy sawtooth is also covered with nichrome coating 6 and the outer surface of almag coating 7
8, composition is Co-based alloy powder, powder size 300-400 mesh, had both increased the active area of screw rod, and had protected the body of rod 5 again not
It is damaged；The front end of the body of rod 5 is connected with head 1, and head 1 acts on actual object surface, and head 5 is connected with pole cap 4 by connector 3
Connect；The screw rod possesses good wear-resisting, corrosion-resistant and high temperature resistant and high-intensity performance, and be unlikely to deform, good operating stability,
The working life of screw rod is extended, improves finished product rate, resource can be greatlyd save, reduce cost.
