Abstract
A COPPER BASE ALLOY WITH SILVER, PHOSPHORUS AND TIN ADDITIONS THAT HAS SELF WETTING PROPERTIES THAT PERMIT DEPOSITION BY WELDING UPON ALUMINUM BRONZE AND MANGANESE BRONZE TYPE BASE METALS.
Description
United States Patent Ofiee 3,674,471 Patented July 4, 1972 US. Cl. 75-153 1 Claim ABSTRACT OF THE DISCLOSURE A copper base alloy with silver, phosphorus and tin additions that has self wetting properties that permit deposition by welding upon aluminum bronze and manganese bronze type base metals.
Heretofore it has been known in the art that it is difficult to weld upon aluminum bronze and manganese bronze type base metals. The surface oxides on the aluminum and manganese bronzes are difiicult to remove and their presence creates difficulties when weld depositing an alloy 'weld deposit on these metals. These difiiculties include unsatisfactory wetting, bond line porosity and surface impurities.
It is the general object of the present invention to avoid the difficulties of the prior art practices by pro viding an alloy with good wetting properties for weld deposition on aluminum and manganese bronzes.
Another object of the present invention is to provide a machineable alloy capable of being weld deposited by flame spraying.
Yet another object of this invention is to provide an alloy for weld deposition on aluminum and manganese bronze base metals without melting the base metal.
Extensive experimental work with copper base alloys led to the discovery that a copper base alloy with phosphorous, silver and tin additions generated exceptional surface wetting properties. In continued experimentation modifications of these alloys were weld deposited by various processes including the flame spraying of a powder (-finer than 25 mesh size) version of these alloys, on base metals of the aluminum bronze class and the manganese bronze class with exceptionally good results. The alloys displayed exceptional surface wetting properties and a melting point that permitted deposition on aluminum and manganese bronze base metals without any melting of the base metals. Further experimentation led to the development of these alloys with the foregoing properties and in addition with good machineability.
The alloys of the present invention comprise the following alloy composition in the weighted percentages indicated:
Balance...
Balance The alloy can be provided as a cast rod or in powder form. The powder can be manufactured by any of the well known processes such as by atomization.
In addition the alloy can be provided upon weld deposition from a heterogeneous powder mixture of several powder alloys finer than 25 mesh size. An example of a heterogeneous powder mixture is the following:
Element Weight percent 0 to 3 by weight of the following alloy powder:
Cr 16.0 Si 4.0
B 3.2 Ni Bal.
mixed with 8 to 12% by weight of the following alloy powder:
Cu 72 Ag 28 mixed with 25 to 35% by weight of the following alloy powder:
Sn 8 P 0.3 Cu Bal It will be understood by those skilled in the art that the foregoing example is oifered only as an example and that a good number of heterogeneous powder combinations can practice the spirit of the invention where a number of alloy powders in a heterogenous combination can weld deposit the invention alloy.
It will now be understood by those skilled in the art that the objects of the invention have been achieved by providing a copper base alloy with exceptional wetting properties.
I claim:
1. An alloy consisting essentially of the following constituents in the weight percentages indicated:
