Definitions
- ABSTRACT The present invention relates to copper base alloys having excellent seizure resistance and wear resistance at high temperatures containing copper as the principal constituent, and zinc (Zn), aluminum (Al), manganese (Mn), silicon (Si), chromium (Cr), and phosphorus (P) as alloy elements;
- the present invention relates to copper base alloys, and more particularly to copper base alloys that have significant wear resistance at elevated temperatures.
- Alloys having excellent wear resistance at high temperatures have long been sought as materials for parts subjected to considerable frictional loads at high temperatures.
- exhaust valve seat materials commonly used today for four cycle automobile engines include cast iron, special cast iron, heat resisting steel and the like.
- these alloys have the disadvantage that when lead-free gasoline, LPG (liquefied propane gas), etc., are used as fuel, they are subject to an unusual wear, lowering of the output of the internal combustion engine, or deterioration of exhaust gas (increase of CO or hydrocarbon). Trouble-free use of these alloys over long periods of time is therefore impossible.
- the present invention relates to copper base alloys excellent in seizure resistance and wear resistance at high temperatures. These alloys are composed of elements within specific composition ranges.
- the alloys according to the present invention are copper base alloys having high wear resistance at high temperatures containing copper as a principal constituent, and from 25 to 40 percent zinc, from .1 to 8 percent aluminum, from 1 to percent manganese, from 0.3 to 2.0 percent silicon, from 0.8 to 3 percent chromium, and from 0.3 to 1 percent phosphorus, and may further contain a small quantity of other elements. (All percentages mentioned in the specification represent weight percent.)
- the copper base alloys according to the present invention are alloys which contain copper as the principal constituent, and zinc, aluminum, .manganese, silicon, chromium and phosphrous as alloy elements, and further may contain a small quantity of other elements.
- the alloys according to the present invention are suitable as fabricating materials for exhaust valve seats used in internal combustion engines, particularly the type that uses lead-free gasoline, LPG, or the like which does not contain additives such as lead.
- the alloy of the present invention is used as a valve seat material, the frictional load is reduced to a negligible quantity. Also, high engine revolutions and high loads and operation during a long engine run can be effected without any difficulty.
- the alloys according to the present invention are also suitable as fabricating materials for components used in a region where dry wear resistance at high temperatures is required, for example, valve-stem guides, synchronizer rings and bearing constructions.
- copper is the principal constituent. It has excellent heat conductibility and anticorrosiveness, and combines with oxygen in the air at high temperatures to form copper oxide.
- a thin film of this copper oxide produces self-lubricating action thereby contributing to the increase of wear resistance of the alloy.
- Zinc dissolves into copper as a solid solution, reinforcing the crystal matrix, and combines as high temperature with oxygen in the air to produce zinc oxide.
- This thin film of zinc oxide also produces selflubricating action and remarkably ameliorates the wear resistance of the alloy. Further, zinc lowers the melting point of alloy and ameliorates its castability. Accordingly, when the reinforcement of the crystal matrix and the castability of alloy is taken into consideration, it is desirable that the content of zinc be more than 25 percent.
- the machinabilty of the alloy is reduced when zinc coexists with other elements which contribute to the reinforcement of the crystal matrix and the wear resistance.
- the content of zinc has been determined to be less than 40 percent.
- Aluminum reinforces the crystal matrix and ameliorates the wear resistance, but since this reinforcement is low in degree, with less than 1 percent aluminum the content of zinc has been determined to be more than 1 percent.
- the machinability deteriorates when it coexits with chromium and the content of aluminum is determined to be less than 8 percent.
- Chromium reinforces the crystal matrix and increases the hardness equally as aluminum. It also contributes to the amelioration of wear resistance. However, with less than 0.8 percent chromium, the effect of aluminum is small, and the content of chromium has been determined to be more than 0.8 percent. Further, with more than 3 percent chromium, the machinability of the alloy decreases, and the content of chromium has been determined to be less than 3.0 percent. As for manganese, it reinforces the crystal matrix in the same manner as in the case of aluminum, and ameliorates the wear resistance, producing at the same time a remarkably hard intermetallic compound conjointly with silicon. This intermetallic compound I is uniformly dispersed in a finely divided state in the crystal matrix thereby remarkably ameliorating the wear resistance.
- the content of manganese has been determined to be more than 1 percent.
- the machinability of the alloy is decreased due to coexistence of manganese with zinc, aluminum, silicon, chromium and the like.
- the content of manganese is determined to be less than 5 percent.
- silicon although it produces a remarkably hard intermetallic compound conjointly with manganese and contributes to the increase of wear resistance of the alloy, the quantity produced of hard intermetal- 3 4 lic compound conjointly with manganese is small and g g; the contribution to the wear resistance is small when 01% the content of silicon is less than 0.3 percent.
- Ti 03 the content of silicon has been determined to be more w 03% arena;
- the machinability of the alloy is lowered due to the coexistence of zinc, aluminum, manganese, chromium and the like.
- the content of silicon is determined to be less than 2 percent.
- Phosphorus is used as a deoxidizer, and with more than 0.3 percent phosphorus it tends to increase the hardness of the alloy and also contribute to the amelioration of wear resistance. However, when the phosphorus content is more than 1 percent, the machinability of alloy decreases. Therefore, the content of phosphorus is determined to be less than 1 percent.
- composition of the alloy B according to the present invention Composition of the alloy A according to the present invention The determination of the was; quantity mentioned 7 above has been effected by fixing an annular specimen that had been heated to 400450C. in an aluminum alloy, rotating it 10 times per minute, imparting by means of a jig made of heat resisting steel repetitive shocks with collision velocity of 0.2m/sec., surface pressure of 30 Kg/cm, and 2,500 turns/min, and determining the variations of thickness of the specimens for a determined period.
- the alloys according to the present invention have extremely excellent wear resistance when compared with ordinary cast iron, special cast iron and heat resisting steel.
- the alloys of the present invention are particularly suitable for fabricating exhaust valve seats which are exposed to extremely high temperatures of the four cycle engines for automobiles which use leadfree gasoline and LPG as fuel.
- a copper base alloy having wear resistance at high temperature consisting essentially of 25 to 40 percent zinc, l to 8 percent aluminum, 1 to 5 percent manganese, 0.3 to 2.0 percent silicon, 0.8 to 3.0 percent chromium, and 0.3 to 1.0 percent phosphorus, and the balance copper.
- a copper base alloy as in claim 1 including additional elements of less than 2 percent of any element selected from the group consisting of iron and nickel, less than 1 percent of any element selected from the group consisting of tin, lead, titanium, zirconium, beryllium, boron, cobalt and tungsten and wherein the total sum of said additional elements is less than 5 percent.
