Description
Multi-element Cu-base solder for soldering low-alloy chilled cast iron belongs to welding material.
White Cast Iron Material has excellent wear resistence because it is cheap, is anti-friction material commonly used in the industrial equipments such as agricultural machinery, electric power, mine and building materials.But therefore white cast-iron, only is fit to be used for making operating rate and be subjected to the lower wear parts of operating mode impulsive force owing to poor toughness.The white cast iron wear-resistant parts often adopt monoblock cast, built-up welding and method manufacturing such as compound.The monoblock cast cost is low, and the wearability height of product, but poor toughness easily form crackle, often loses efficacy in advance, scraps because of brittle failure before wearing and tearing.At steel surface overlaying white cast-iron, because the welding temperature height, parts easily produce distortion, and the commissure easily forms crackle even snaps.Composite is subjected to certain restriction again in operations such as planform, machined.Soldering is through being usually used in the method that dissimilar metal connects because welding temperature is lower, and tissue and performance impact to material after the soldering are less.White cast-iron is hard and crisp, thinks both at home and abroad always, and the white cast-iron soldering is nonsensical.In recent years, because every combination property of white cast-iron is improved, become important high-abrasive material.Therefore, the Application and Development for the good white cast-iron soldering parts of cheapness, high rigidity, mar proof has bigger economic benefit.At present, be suitable for becoming the solder of wear parts that two classes are arranged with the carbon steel soldering white cast-iron: a class is a silver-base solder, and a class is a copper base solder.Documents and materials with above-mentioned solder brazing white cast-iron are not seen report as yet.The silver-base solder fusing point is low, and processing performance is good, soldered fitting intensity height, but too high with its brazing white cast iron cost.Copper base solder is compared with silver-base solder, and cost is low, but solder fusing point height, processing performance is poor, and the brazing white cast iron strength of joint is low.The lower copper base solder of having developed of some fusing points is mainly used to brazed copper, copper alloy and steel both at home and abroad, is not suitable for brazing white cast iron.
It is lower to the purpose of this invention is to provide fusing point, high comprehensive performance, multi-element Cu-base solder for soldering low-alloy chilled cast iron with low cost.By the method for soldering, wear-resistant white cast iron and steel are coupled together, make wear parts.
Above-mentioned purpose of the present invention is achieved in that multi-element Cu-base solder for soldering low-alloy chilled cast iron, and it comprises Cu, and Zn is characterized in that adding Mn, Ni, Si, each composition percentage by weight is: Zn 20-30, Mn 6-12, Ni 0.5-2, Si 0.2-1.0, Cu surplus.
Multi-element Cu-base solder for soldering low-alloy chilled cast iron, it comprises Cu, Zn, Mn, Ni, Si is characterized in that also containing Sn, each composition percentage by weight is: Zn 30-40, Mn 4-8, Ni 1-3, Si 0.5-1.5, Sn 2-6, Cu surplus.
Multi-element Cu-base solder for soldering low-alloy chilled cast iron, it comprises Cu, Zn, Mn, Ni, Si is characterized in that also containing Re, each composition percentage by weight is: Zn 30-40, Mn 6-12, Ni 1-3, Si 0.4-1.2, Re 0.2-0.8, Cu surplus.
Multi-element Cu-base solder for soldering low-alloy chilled cast iron, it comprises Cu, Zn, Mn, Ni, Si is characterized in that also containing Sn, Re, each composition percentage by weight is: Zn 20-42, Mn 4-12, Ni 0.5-3.5, Si 0.2-1.5, Re 0.1-1.0, Sn 2-8, Cu surplus.
The multi-element Cu-base solder prescription series that this invention provided to the selection of its composition, can specifically become the component selections different series according to brazing white cast iron.
The present invention has the following advantages: compares with the existing white cast iron wear-resistant component technology of making, and less because the soldering welding temperature is lower to spoken parts in traditional operas structure of cast iron and Effect on Performance, be fit to very much the production of small-sized brazing white cast iron wear parts.Its formulation cost is low, and fusing point is moderate, and the brazing white cast iron processing performance is good, and white cast-iron and the interface densification of drill rod seam have higher strength of joint.This solder not only can be used for white cast-iron and be connected the production wear parts with steel, can also be used for the soldering of cast steel and spheroidal graphite cast-iron.
Further specify details of the present invention and machining process below in conjunction with embodiment.
The present invention is on the basis of copper base solder, and through experiment in a large number, apolegamy adds an amount of alloying element, to obtain to be fit to the brazing material of brazing white cast iron.The effect of the alloying element that adds in multi-element Cu-base solder is: the adding of Mn, form low melting point solid solution with Cu, and can reduce the solder fusing point, improve brazed seam intensity.Add Si, can suppress the volatilization of Zn in the solder.Add Ni, can improve the moulding of solder, toughness and brazed seam intensity and wettability.Add Sn, can reduce the solder fusing point and improve solder wetting.Add Re, can improve solder wetting performance and solder intensity.
