Description
Technical field
The invention belongs to the metal material engineering technical field, relate to high temperature brazing sintered carbide tools technical field, specially refer to a kind of high performance bond.
Background technology
Chemical metallurgy combination when high temperature brazing CBN emery wheel utilizes soldering between matrix-bond-abrasive particle has fundamentally been improved intensity has been controlled in the combination of abrasive material, abrasive material does not come off substantially in the process, satisfy the needs of high-efficiency and precision processing operation, helped the improvement of machined surface roughness; Simultaneously, high temperature brazing CBN emery wheel has shape hold facility preferably, can avoid drawbacks such as the uniformity interchangeability relatively poor, workpiece of the workpiece accuracy that multilayer instruments such as resinoid bond or vitrified bond need often repair, process is bad.The titanium alloy chemism is big, and thermal conductivity is low, belongs to typical difficult-to-machine material, is easy to stick in grinding process.Replace traditional emery wheel machining titanium alloy with the CBN emery wheel and obtained certain effect.When machining titanium alloy, to the demands for higher performance of high temperature brazing CBN emery wheel, not only to satisfy surface of the work integrality and dimension precision requirement, also require abrasive dust to be easy to come off from wheel face, do not stick, guarantee the long-time reliability service of emery wheel.Therefore the bond of high temperature brazing CBN emery wheel is had higher requirement, not only will have good wettability, guarantee firm being welded on the matrix of abrasive particle, require it to be difficult for sticking simultaneously with the titanium alloy abrasive dust to abrasive material and matrix.Metallic bond silver-bearing copper titanium commonly used has very big affinity owing to contain titanium with abrasive dust, but titanium is again bond and abrasive particle generation chemical reaction, the important element of realizing the chemical metallurgy combination, the content reduction can influence the intensity of controlling to abrasive particle, and then reduces wheel life.
Rare earth has very high chemism, be a kind of typically, very active metal, have and breed and go bad, strengthen, improve heat resistance and improve effect such as processing performance, obtained to use widely at metallurgy and material field.
Summary of the invention
The objective of the invention is to, a kind of high temperature soldering CBN grinding wheel used metal combination dose layer material that adds rare earth La is provided, it is by adding the combination property that rare-earth elements of lanthanum (La) improves bond in high temperature brazing CBN emery wheel metallic bond, simultaneously, improve the performance of high temperature brazing CBN emery wheel guaranteeing that abrasive particle controls the content that reduces titanium elements on the intensity based.
The high temperature soldering CBN grinding wheel used metal combination dose layer material of the interpolation rare earth La of the present invention's design is characterized in that: its chemical composition mark proportioning by weight is: 20%~30% copper (Cu), 2%~7% titanium (Ti), 0.05%~1.0% lanthanum (La), all the other are silver (Ag).
The preferred range of lanthanum of the present invention (La) is 0.1~0.5%.
Bonding agent layer material constituent element of the present invention is less, and wettability is good, because the adding of rare earth element, refinement intermetallic compound, make organizing of bond more even, improved the intensity of bond, high comprehensive performance can satisfy the requirement in sintered carbide tools high temperature brazing field.
