Abstract
The extremely anticorrosive cylinder liner for engine is made of double-phase stainless steel comprising one half of ferrite and one half of austenite in the solid solution structure. The working surface is ionic nitrizing treated at 550-650 deg.c to form nitride layer of 0.02-0.12 mm depth. The cylinder liner of the present invention is superior to available ones, which have the demerits of cavitation erosion, erosion fatigue cracking, short life and great friction power consumption.
Description
Technical field:
The invention relates to the parts of motor, particularly about the cylinder liner of motor.
Background technique:
Cylinder is to be the main place of mechanical work with the thermal power transfer of working medium in the motor, because its residing working environment and body and other part have greatest differences, and the needs of making, often occur with the form of cylinder liner (see figure 1) a important spare part as motor.In internal-combustion engine, cylinder liner mainly consider and piston between the damage that friction caused, so adopt materials such as the cast iron of low coefficient of friction such as gray cast iron, low-alloy cast iron, high phosphorus alloy cast iron, boron cast iron to make cylinder liner usually; In addition, also adopt nitriding processes such as gas nitriding, nitrocarburizing to improve its wear resistance and bite-resistant ability.But the material of cast iron class not only intensity is low, and corrosion resistant poor performance, cavitation pitting and erosion fatigue cracking take place easily, therefore the cylinder liner material of the heat engine (for example Stirling heat engine) of heat supply beyond being not suitable for doing, this is because the working pressure of heat engine working medium is higher than internal-combustion engine, and its periphery is cooled off by cooling medium, so cylinder liner mainly produces erosion fatigue cracking because of surface etching easily under high alternating stress effect.The cylinder liner of heat engine is used the high middle carbon chrome molybdenum structural steel of intensity always for this reason, and what generally adopt at present is that the trade mark is the 38CrMoAlA CrMo aluminium steel.But these materials are unsatisfactory, and service time one is long, and its top layer that contact with cooling medium is erosion fatigue cracking very easily, cause working medium leakage and losing efficacy easily, thus lack working life, generally only about 1000 hours.
Summary of the invention:
The invention reside in provides a kind of motor with super anti-corrosion cylinder liner, and cavitation pitting, erosion fatigue cracking, working life is short, friction horsepower is big technical problem take place solution available engine cylinder liner easily.
The technological scheme that the present invention solves the problems of the technologies described above is as follows:
The super anti-corrosion cylinder liner of a kind of motor, it is characterized in that: this cylinder liner material is the two phase stainless steel that ferrite and austenite respectively account for half in the solid solution structure, working surface carries out ionic nitrizing treatment under 550 ℃～650 ℃ conditions, nitride layer depth is 0.02～0.12mm.
Described motor is characterized in that: need to anneal under 550 ℃～650 ℃ temperature before plasma nitriding, eliminate stress with super anti-corrosion cylinder liner.
Described motor is with super anti-corrosion cylinder liner, and it is characterized in that: the roughness of its working surface should be machined to Ra0.4 before nitrogenize, polish after the nitrogenize/super grinding handles to Ra0.2.
The present invention is used to make cylinder liner with ferrite in the solid solution structure and the about two phase stainless steel via nitride processing that respectively accounts for half of austenite first, has obtained significant technique effect.Its advantage is as follows:
1. have the super decay resistance under high alternating stress,, do not see corrosion or cavitation pitting through 2000 hours endurance test.
2. rub little, wearing and tearing extremely slight.
3. prolong working life more than 1 times.
4. can be applied to simultaneously in two kinds of dissimilar motors of internal-combustion engine and heat engine.
Description of drawings:
Fig. 1 is the structural representation of general cylinder liner.
Embodiment:
The model that the present invention adopts ferrite and austenite in the solid solution structure respectively to account for half approximately is the cylinder liner that two phase stainless steels such as 00G18Ni5Mo3Si2 or 00Cr18Ni5Mo3Si2Nb, 00Cr22Ni5Mo3N or 00Cr25Ni6Mo2N are made motors (comprising internal-combustion engine and heat engine).Cylinder liner need be eliminated the annealing in process of its internal stress earlier, and the temperature of annealing is 550 ℃～650 ℃, and the working surface of its internal diameter is carried out fine finishing, makes the roughness of this working surface reach Ra0.4.Then cylinder liner is carried out plasma nitriding under 550 ℃～650 ℃ temperature conditions, make working surface of the present invention have the nitride layer of 0.02～0.12mm thickness.
The present invention needs its working surface is polished or super grinding processing after plasma nitriding, makes the roughness of working surface reach Ra0.2.
