Abstract
The invention discloses a novel steering rudder rudder bearing hole wear-resistant layer alloy material which is prepared from the Ni-Cu-P ternary alloy material and comprises the following components by weight percent: 65-70% of Ni, 15-20% of Cu and 10-15% of P. Cu is introduced into the Ni-P chemical plating solution to bring the change of the content of P in the plating, thereby influencing the microstructure and crystallization of the Ni-Cu-P chemical plating, improving the thermal stability, weldability and corrosion resistance of the plating, increasing the service life of the whole rudder blade by 3-5 years, reducing the rudder replacement frequency for large ships, reducing the maintenance cost of ships and enabling the ships to create more economic benefits.
Description
Technical field
The present invention relates to a kind of alloy material, relate in particular to the alloy material of the steering rudder rudder bearing pore area alloy wear-resisting layer use of a kind of suitable large ocean ships that transport, engineering ship and inland navigation craft use.
Background technology
Turn to rudder to be mounted in the propeller for vessels rear, in the normal driving process of boats and ships, turn to the direction of rudder consistent with the navigation direction, when in case boats and ships need turn to, turn to rudder rotating certain angle under the effect of power, and the thrust that produces by water screw changes side force into, the promotion ship turning.At present, at home and abroad the rudder bearer material of rudder mostly is 20Mn greatly, and its performance is similar to the 15Mn steel, and hardening capacity, intensity and plasticity are all good than No. 20 steel, and cutting ability also increases, and low-temperature impact toughness and welding property are good.But its wear resistance, erosion resistance is all relatively poor, because large ocean ships that transport, engineering ship travels in the ocean mostly, seawater has corrodibility, therefore considerable influence turn to work-ing life of rudder, the work-ing life that generally turns to rudder is at 20-25, just must change when turning to rudder to erode to a certain degree, the each replacing needs a large amount of time and moneys, large ocean ships that transport particularly, whenever its loss in a day of suspending is sizable, for wear resistance and the non-corrosibility that improves steering rudder rudder bearing hole, electroless plating one deck alloy wear-resisting layer on the rudder bearer hole, the plating Ni-P alloy material that is adopted in the market, but Ni-P alloy material thermostability plated, weldability and erosion resistance are relatively poor, can't reach the ideal effect.
Summary of the invention
The object of the present invention is to provide a kind of novel steering rudder rudder bearing hole wear-resistant layer alloy material, adopt Ni, Cu and P ternary-alloy material, Cu is introduced in the Ni-P chemical plating fluid, improve thermostability, weldability and the erosion resistance of coating, make increase 3-5 the work-ing life of whole rudder blade, make boats and ships can create bigger economic benefit.
Technical scheme of the present invention is achieved in that
A kind of novel steering rudder rudder bearing hole wear-resistant layer alloy material is become to be grouped into for three kinds by Ni, Cu and P, and the weight percent of each composition is: Ni65-70%, Cu15-20%, P10-15%.
By 45
#Steel plate (300mm * 200mm * 12mm) go up alloy plating coating to test, the bonding force of coating (1) file trace and thermal shock method: the plating sample is filed seamed edges with file with 45 jiaos under plated state, smooth and the non-scale of file trace, use thermal shock method (will plate sample and in box-type furnace, heat and cut out 200 ℃, and be incubated 20 minutes, and take out Quench in the water that immerses room temperature immediately) then, mensuration shows after 7 circulations, the no segmentation crack in plating sample surface proceeds to 15 times, and the surface does not still have peeling.(2) bending method: at diameter is on the wire rod of 8mm, and behind crooked 180 degree, the result shows not have peels off flawless.(3) thermal treatment to structure of plating layer and microhardness influence sample plating after after the differing temps tempering, coating is carried out x ray diffraction analysis x, and measure its microhardness, the result shows that the hardness of alloy plating coating is 520-650.
The present invention compared with prior art has following advantage:
Adopt Ni, Cu and P ternary-alloy material, Cu is introduced in the Ni-P chemical plating fluid, cause the variation of P content in the coating, thereby influence the microstructure and the crystallization behavior of Ni-Cu-P chemical plating, improve thermostability, weldability and the erosion resistance of coating, make increase 3-5 the work-ing life of whole rudder blade, reduce large ship and change the frequency that turns to rudder, reduce the maintenance cost of boats and ships, make boats and ships can create bigger economic benefit.
