Abstract
The invention discloses an automobile emission device connector nitrided, comprising a body. A nitriding process is provided. The body is in a square structure; the front and tail ends of the body are provided with square air holes, namely a left air hole and a right air hole; a connecting crosspiece is disposed in the middle of the left air hole; the center of the bod is in a hollow structure. The nitriding process includes: performing gas deoiling first before nitriding, subjecting the surface to sandblasting with alumina powder, placing a treated part in a nitriding furnace, and closing a furnace cover before heating. The automobile emission device connector nitride has the advantages of excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance.
Description
Technical field
The present invention relates to a kind of engineering goods, is a kind of motor vehicle emission device link of via nitride processing specifically.
Background technique
Some motor vehicle emission device links on existing market, due to the automobile engine to exhaust hole of ining succession, gas is just discharged in a flash, and temperature is higher, very large to whole hot-air channel erodibility, easily causes the damage of automobile hot-air channel.
Summary of the invention
The invention provides a kind of motor vehicle emission device link of via nitride processing.
The object of the invention is to solve more existing motor vehicle emission device links, due to the automobile engine to exhaust hole of ining succession, gas is just discharged in a flash, and temperature is higher, very large to whole hot-air channel erodibility, easily causes the problem of the damage of automobile hot-air channel.
The technical solution adopted for the present invention to solve the technical problems is: a kind of motor vehicle emission device link of via nitride processing, comprise the process of body and nitriding treatment, described body is made as square structure, it is provided with square vent in two ends end to end, be respectively left vent and right vent, in the middle of described left vent, be provided with one and connect crosspiece, in the middle of described body, be made as hollow-core construction, described nitriding treatment comprises, first nitriding deoils with gas before processing, then use alumina powder that sand blast is done in surface, then more processed part is placed in to nitriding furnace, and will after bell sealing, can heat, but before being heated to 150 DEG C, must do deaeration work in stove, after nitriding completes, heating power supply is closed, make furnace temperature reduce approximately 50 DEG C, then after the flow of ammonia being doubled, start breakdown heat exchanger, wait the ammonia importing in stove stable after, the flow that can reduce ammonia is to keeping in stove till malleation, in the time that furnace temperature drops to below 150 DEG C, can breakdown bell after importing air or nitrogen.The present invention is through having excellent wear resistance, fatigue resistance, corrosion resistance and resistant to elevated temperatures characteristic after nitriding treatment.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in the figure, the present invention includes the process of body 1 and nitriding treatment, described body is made as square structure, it is provided with square vent in two ends end to end, be respectively left vent 5 and right vent 3, in the middle of described left vent 5, be provided with one and connect crosspiece 4, in the middle of described body, be made as hollow-core construction 2, described nitriding treatment comprises, first nitriding deoils with gas before processing, then use alumina powder that sand blast is done in surface, then more processed part is placed in to nitriding furnace, and will after bell sealing, can heat, but before being heated to 150 DEG C, must do deaeration work in stove, after nitriding completes, heating power supply is closed, make furnace temperature reduce approximately 50 DEG C, then after the flow of ammonia being doubled, start breakdown heat exchanger, wait the ammonia importing in stove stable after, the flow that can reduce ammonia is to keeping in stove till malleation, in the time that furnace temperature drops to below 150 DEG C, can breakdown bell after importing air or nitrogen.The present invention is through having excellent wear resistance, fatigue resistance, corrosion resistance and resistant to elevated temperatures characteristic after nitriding treatment.
