Description
Technical field
The present invention relates to a kind of die steel matrix alumina reinforced composite surface strengthen layer, belong to surfacing preparation and Surface-micromachining process field, particularly a kind of nickel and nickelalloy aluminum oxide reinforced composite surface strengthen layer preparation method.
Background technology
Die steel 4Cr5MoSiV1 (being commonly referred to as H13) is because containing higher carbon and vanadium, and this steel has high hardening capacity, thermal crack resistant ability, good thermotolerance and heat resistance and higher anti-temper resistance.Based on the good over-all properties of this steel, all be widely applied aspect hammer forging die, hot extruding die and transfer mold.But because the working conditions of die steel is severe, not only to repeatedly experience high temperature-low temperature thermal cycling effect, and to bear larger repeated stress, make die surface usually because of wearing and tearing or thermal fatigue generation defect, one of key technical problem that so die surface strengthening (life-prolonging technique) and defect repair are relevant enterprises always will be solved (Song Qiang etc.: plasma spray wear-resistant coating preparation and property is analyzed. Nanjing University of Technology's journal, 2009,31 (5), 102-105).
The die surface strengthening life-prolonging technique is the wear-resisting modified layer of die cavity damageable zone deposition one deck at mould, after modification, the mould working-surface has high hardness, and inside still has good toughness, thereby can improve the use properties of mould, give full play to the performance potential of moulding stock.The mould repair technology is that the position that mould has damaged is repaired, and makes its reinstatement (shape and performance), the mould after processing treatment can continue to use, thereby has extended the work-ing life of mould.At present, die surface reparation commonly used or the major project means of strengthening have carburizing or the methods such as nitriding, arc surfacing, electric spark deposition, Brush Plating and laser melting coating.In the processing method for preparing the die surface repair layer, arc surfacing is often very large due to heat input, and the heat affected zone of causing on mould is very large being repaired, and easily causes die deformation even to ftracture; The electric spark deposition method, because the bond quality of settled layer and matrix is uncertain, particularly porosity and compactness are discontinuous, and some intends the repair materials of use, as the alloy system complicated component, or, for high rigidity, high-strength material, be difficult to be processed into silk material or the bar of electrode requirement, and when the reparation amount is larger, production efficiency is extremely low, rehabilitation cost very high (Xu Dong etc.: the application of electric discharge surface treatment technology on mould. the equipment manufacturing technology, 2010,4:150-153); For the Brush Plating method, coating is generally very thin, mostly be less than 0.3mm, and because the combination of coating and matrix is a kind of mechanical bond, so lower with substrate combinating strength, the practical application of above the whole bag of tricks is very limited (Zhao Weilin etc.: Brush Plating and the surfacing of vehicle mould are repaired fast. mould industry, 2007,33(2), 64-66); Laser cladding is because equipment is once invested greatly, promotion and application also have certain difficulty (Jiang Shengbo etc.: forge die coating structure and performance study are scrapped in the laser melting coating reparation. the material heat treatment technology, 2009(38), 86-88).
Summary of the invention
Technical problem to be solved by this invention is to have overcome problems of the prior art, a kind of nickel and nickelalloy aluminum oxide reinforced composite surface strengthen layer preparation method are provided, adopt the plasma spray welding technology on the die steel surface, to prepare the composite surface layer of nickel and the enhancing of nickel alloy base aluminum oxide, reach the effect of rectification of defects or strengthening matrix, recover and extend the work-ing life of mould.
For solving the problems of the technologies described above, the present invention adopts following technical scheme to realize, accompanying drawings is as follows:
The present invention is the powder alloy material (C:0.6 that adopts specific chemical composition, Si:3.0, Cr:12.8, B:2.6, Fe:7.5, WC:22, Co:3, Ni:46.5) with aluminium sesquioxide mechanically mixing carry out ball-milling processing, making its size range is 40 μ m-100 μ m, utilizes plasma spray welding technology to prepare the composite repair layer on the die steel surface.
A kind of nickel and nickelalloy aluminum oxide reinforced composite surface strengthen layer preparation method, concrete steps are as follows:
1) the die steel matrix surface is cleared up, the surfacing powder that one-tenth distributes is put into to powder feeder;
2) plasma spray: the mixed gas that the hydrogen of employing 25% and 75% argon form, current setting is 25A, after arc stability, starts the automatic powder feeding surfacing, controls spray gun translational speed and powder feeding rate to obtain the satisfactory spray-welding coating of thickness;
3) lap of controlling between the spray gun spraying track is 20% of single spraying profile width, makes spray-welding coating smooth surface, smooth.
Described surfacing powder is 85% Co-based alloy powder and 15% aluminium sesquioxide miscellany.
