Abstract
A composite ceramic film cylinder liner for a locomotive diesel engine belongs to the technical field of cylinder liners and aims to have ductility, corrosion resistance, wear resistance and oxidization resistance on the surface of a base so as to prolong service life of the cylinder liner. The composite ceramic film cylinder liner is technically characterized in that a BN-SIN composite ceramic film layer (2) is permeated on the surface of the inner wall of the cylinder liner (1). The BN-SIN ceramic film is a network structured novel material made by using the ultrafine plasma PCVD technique, by adopting the low temperature plasma PCVD technique at the temperature of lower than 350 DEG C, the BN-SIN ceramic film and the metal base of the inner wall of the cylinder liner diffuse with each other, deposit and grow into a composite ceramic film, and the composite ceramic film not only has high binding force, but also greatly increases ductility, wear resistance, oxidization resistance and corrosion resistance of the cylinder liner, thereby greatly prolonging service life of the cylinder liner.
Description
Technical field
The utility model relates to a kind of ceramic thin sheet cylinder liner that is used for diesel engine of locomotive.
Background technique
As everyone knows, the cylinder liner of diesel engine of locomotive and cylinder head, piston are formed the firing chamber of diesel engine jointly.Maximum temperature during fuel gas buring in the firing chamber can reach about 1500 ℃, maximum combustion pressure is general all more than 10Mpa, the combustion gas of this High Temperature High Pressure not only can cause cylinder bore wall the temperature difference pressure of bigger alternation to be arranged (in the intake process, intake temperature is below 100 ℃, so inboard wall of cylinder liner is subjected to is the effect of 100--1500 ℃ transition temperature.Outer wall of cylinder jachet is a water cavity, the temperature of cooling water is generally about 70 ℃, makes the casing wall cross section that bigger temperature gradient be arranged), also can play the effect of washing away to the oil film of casing wall with sintering, thereby aggravated the wearing and tearing of inboard wall of cylinder liner, shortened the working life of cylinder liner.
Summary of the invention
The purpose of this utility model is to provide a kind of matrix surface to have the ceramic thin sheet cylinder liner that is used for diesel engine of locomotive of toughness, corrosion resistance, wear resistance and oxidative stability, to prolong the working life of cylinder block.
Its technological scheme is: a kind of ceramic thin sheet cylinder liner that is used for diesel engine of locomotive is characterized in that: inner wall surface infiltration one deck BN-SIN ceramic thin sheet of described cylinder liner.
Its technique effect is: because the BN-SIN ceramic thin sheet is a kind of new material with network structure that adopts ultramicron plasma P CVD technology to develop.Therefore, adopt low temperature plasma PCVD technology being lower than under 350 ℃ of conditions, make the BN-SIN ceramic membrane with cylinder liner metal base surface generation interdiffusion mutually, deposit, grow into ceramic thin sheet, it is the combination force height not only, and improved toughness, wear resistance, anti-attrition, oxidative stability and the corrosion resistance of cylinder liner greatly, prolonged the working life of cylinder liner significantly.Detect through on probation, the more conventional cylinder liner of its durability improves 2-4 doubly.And because the thickness of BN-SIN ceramic thin sheet is less than 3 μ m, so after the infiltration, the size of cylinder liner, shape are almost constant, do not influence its precision and assembly performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, be lower than under 350 ℃ of conditions, adopt low temperature plasma PCVD technology, at the metal base surface of cylinder liner 1 inwall infiltration one deck BN-SIN ceramic membrane, make BN-SIN ceramic membrane and cylinder sleeve inwall metallic matrix generation interdiffusion mutually, deposit, grow into ceramic thin sheet 2.
Claims (1)
1. a ceramic thin sheet cylinder liner that is used for diesel engine of locomotive is characterized in that: inner wall surface infiltration one deck BN-SIN ceramic thin sheet (2) of described cylinder liner (1).
