Description
Technical field
The present invention relates to ceramic technology field, particularly relate to a kind of hydraulic steel pipe and add the ceramic lining material of cerium oxide metal nickel powder.
Background technology
The pipeline kind used in hydraulic system is a lot, according to operating pressure and the difference of installation site of hydraulic system, selection have steel pipe, copper tube, rubber tube, nylon tube and plastic tube etc..These pipelines once damage leakage of oil, the most then pollute environment, affect the normal performance of systemic-function, heavy then jeopardize safety, and the present invention selects hydraulic steel pipe as object of study.When hydraulic work system, fluid pressure line to bear higher pressure, add alternate stress that pressure transient produces, vibration equipment and produce vibration stress, the common effect of erection stress etc., make hard tube at fault in material, hot spot or injury region produce stress concentration phenomenon, pipeline generation fatigue rupture fracture and leakage of oil；Due also to hydraulic system is easily contaminated, the hydraulic oil containing solid pollutant is similar to the grinding agent that abrasive metal machined surface is used, and adds the friction of fluid and pipeline inner wall.And the hardness of the usual hardness ratio pipe inner wall material of solid pollution composition granule is much higher, thus accelerate the abrasion of pipe inner wall, even scratch inwall, particularly high when the flow velocity of liquid and unstable time, the material of pipe inner wall will be made to be impacted and peel off.These reasons easily cause potential safety hazard.
Centrifugal SHS technology has concentrated the Common advantages of centrifugal casting and SHS technology, and it has manufacturing process and manufacture equipment is simple and production efficiency is high, production cost is low and saves the advantages such as the energy.Utilizing centrifugal self-propagating synthesis technology to prepare ceramic lining material inside tradition stainless steel tube can make hydraulic oil oil pipe have more preferable corrosion resistance, abrasion resistance properties and good mechanical property and shock resistance.Thus, the preparation that this kind of technology is applied to hydraulic oil oil tube inner lining material will have wide market prospect and huge economic and social benefits.With micron aluminium powder and micron iron sesquioxide as primary raw material in " preparation of hydraulic oil oil pipe ceramic lining material and performance study " literary composition, with micron silica and micron Y-ZrO2 as additive, using centrifugal SHS technology to be prepared for hydraulic oil oil pipe ceramic lining material, prepared hydraulic oil oil pipe ceramic lining material has the performances such as good toughness, fracture strength, impact resistance.But owing to self-propagating reaction is the fiercest, in course of reaction, thermal losses is big, the finite thickness that steel pipe inner wall is melted, cause the bond strength of metallurgical binding part limited and there is certain hole, so the tools such as the thermostability of ceramic layer, corrosion resistance, wearability are had a certain impact, under the operating mode of some HI high impacts, there will be the phenomenon that ceramic coating comes off, thus affect service life and the safety coefficient of oil pipe, need to improve on the basis of original text.
