The invention solves some insufficiencies in the high-temperature brazing technique with high manufacturing efficiency, which is easy to control for automation manufacturing.
Description
Technical field
The invention belongs to the high temperature brazing technical field, relate to improvement high temperature brazing diamond abrasive grain method.
Background technology
Diamond (Diamond) is the simple substance of carbon (C), axial plane heart cubic systems such as its crystal structure genus, unique crystal structure make diamond have hardness the highest in the nature material, rigidity and good resistance to wear, corrosion resistance and chemical stability.The physical mechanical characteristic of diamond excellence has determined that it is desirable raw material of making the hard brittle material machining tool, is widely used in drill bit, cutting tools, grinding tool, grinding tool miscellaneous and other important superhard wear surface of hard brittle materials such as carbide alloy, engineering ceramics, optical glass, semi-conducting material, granite.
Individual layer high temperature brazing skive manufacture craft mainly relies on vacuum brazing to finish at present, but there is following limitation in actual applications in vacuum brazing: brazing process heats, cool time is long; Cause the cycle of production elongated, time-consuming power consumption, diamond abrasive is in for a long time and can makes the abrasive particle surface unfavorable product occur under the hot environment, be subjected to the furnace chamber size restrictions simultaneously, can't the large-scale instrument of soldering, be difficult to also be implemented in simultaneously that it was out of shape uppity instrument manufacturing when matrix bore whole heating.
Adopt the fast laser of energy density height, warming and cooling rate as thermal source, can local heat, the heat affected area is little, but the workpiece of soldering complex geometry, and therefore laser beam available fiber transmission can process at the position that usual manner is difficult for soldering, and flexibility is good, the time that the while diamond exposes under hot environment is very short, and this has just effectively controlled adamantine graphitization.The laser braze welding process can be carried out the Based Intelligent Control of automatic flow by software, thereby realizes high-efficiency automatic, intelligent laser soldering, production efficiency height in extensive the manufacturing.
Summary of the invention
The object of the present invention is to provide a kind of method of laser braze welding diamond abrasive grain, to solve problems such as the braze cycle that exists in the vacuum brazing is long, doctor is size-constrained.Technical scheme of the present invention is: a kind of manufacture method of nickel base brazing filler metal laser braze welding diamond abrasive grain, and the laser braze welding equipment based on CO2 laser instrument, numerical control machine tool, gas shield device are formed is characterized in that:
45 steel matrix that process are put into organic solvent with no plated film diamond carry out the ultrasonic wave cleaning; again according to 45 steel matrix/three layers of sequentially built sample to be processed of nickel-based solder/diamond abrasive grain; sample is inserted on the brazing equipment of forming by CO2 laser instrument, machining tool and gas shield device then; under the CO2 laser action; the nickel-based solder melted by heat; combine with matrix and diamond generation chemical metallurgy, realize nickel base brazing filler metal laser braze welding diamond abrasive grain.
The power of laser instrument is adjusted into 700-850W, and laser scanning speed is 20-45mm/min, and the laser facula area is 15-21mm2.The parameter of best laser braze welding diamond abrasive grain is: the power 780W of laser instrument, sweep speed 30mm/min, laser facula area are 18mm2.
Nickel-based solder diffuses to form chemical metallurgy mutually with element in 45 steel matrix and combines in the junction; Cr element in the nickel-based solder is in the diamond interface enrichment, and generates Cr3C2 with C element reaction in the diamond.
Description of drawings
Fig. 1 is the joint piece assay maps that 45 steel matrix are processed into
Fig. 2 is the assay maps to be processed by 45 steel matrix/three layers of sequentially built of nickel-based solder/diamond abrasive grain
The specific embodiment
Embodiment: 45 steel matrix are processed into as shown in Figure 1 joint piece sample; Suitably polish with the 100# abrasive paper for metallograph for its to be brazed, for eliminating the influence of various unclean factors, diamond abrasive grain and 45 steel matrix are put into organic solvent respectively carries out ultrasonic wave and cleans, before the soldering, according to 45 steel matrix/three layers of order of nickel-based solder/diamond abrasive grain, 40/50 order is not had the plated film diamond and nickel-based solder is precoated on 45 steel surfaces, carry out laser braze welding after the drying, as shown in Figure 2.
Laser braze welding technological parameter: optical maser wavelength 10.6 μ m, multimode rectangular light spot, area 18mm2, laser power 780W, sweep speed 30mm/min.Through finding behind the physico-chemical analysis: solder layer is sprawled evenly behind the laser braze welding, and nickel-based solder shows good wellability to diamond abrasive grain, and the crystalline form of diamond abrasive grain is complete after the soldering, and corner angle are clearly demarcated, flawless.
With the diamond abrasive grain of postwelding, etch some hrs in strong acid is observed interface product form by SEM.Can be clear that on the diamond surface veneer comparatively flat strip shaped product of rule of growing.Through the X-ray diffraction material phase analysis, as seen there is Cr3C2 to generate at diamond surface,
Element to nickel-based solder and 45 steel matrix interfaces is analyzed, Ni, Cr, Si, Fe element all present transition trend slowly in concentration gradient at the interface, these explanation nickel-based solder and 45 steel matrix are existing tangible diffusion phenomena at the interface, can think that thus having formed chemical metallurgy between nickel-base alloy solder and the steel matrix combines.
Joint piece after the soldering is carried out heavy load grinding test on granite, the result shows that diamond abrasive grain is normal wear, does not have whole diamond drop-off, illustrate matrix to diamond abrasive grain to control intensity very high.
