Background technology
Piston rod common used material is 35,45, the steel such as 38Cr, quenched after roughing, hardness is up to 230 ~ 285HBS but resistance to
Mill property it is poor, high-frequency quenching need to be carried out, there are problems that crackle it is many, harden hardness it is low,；Easily in long-term motion
During with surrounding medium occur chemical reaction and electro-chemical reaction and corroded, corrosion resistance is poor.
The content of the invention
It is an object of the invention to overcome the shortcomings of prior art exist, and provide it is a kind of have case hardness higher, wearability,
Fatigue strength and preferable corrosivity, enable piston rod to be used in high-corrosion medium for a long time, and keep operating accuracy
With service life.
The purpose of the present invention is completed by following technical solution, a kind of for compressor piston rod friction surface
Processing and treating method, the piston rod select 05Cr17Ni4Cu4Nb stainless steel materials, the piston rod sectional dimension≤
200mm, mechanical property Rm >=930MPa, Rel >=725Mpa, A >=16%, Z >=50%, hardness HBS >=227, the piston rod warp
Cross forging solution treatment, roughing, heat treatment cancellation stress, semifinishing, heat treatment cancellation stress, corase grind rubbing surface, spraying
Treatment, finishing；The spray treatment that described piston rod friction surface is carried out is：Supersonic is selected to the piston rod friction surface
Fast sprayed wc carries out spray treatment, profile depth 0.25 ~ 0.35mm, HRC ＞ 55.
As preferred：Described roughing is mainly and piston rod is made drill centers, the treatment of rough turn Excircle machining；Described
The semifinishing stage is to carry out this finishing processing treatment to piston rod surface；Described finishing is to carry out essence to piston rod surface
Turning, cylindrical, the fine cylindrical working process of corase grind；Described spray treatment, be first by piston rod be divided into Spray Application and
Protection part, and after protection part is taken into effective protection measure, the Spray Application to piston rod friction surface is sprayed
Treatment.
The present invention is the improvement to existing process, piston rod is had case hardness higher, wearability and fatigue strength,
And with good heat resistance and corrosivity, to keep the operating accuracy and service life of piston rod, 05Cr17Ni4Cu4Nb is not
Rust steel, with high intensity, hardness and the characteristic such as anticorrosive, mechanical performance is more perfect after Overheating Treatment.
The present invention has case hardness higher, wearability, fatigue strength and preferable corrosivity, piston rod is existed
The features such as being used in high-corrosion medium for a long time, and keep operating accuracy and service life.
Specific embodiment
