Abstract
The invention is a sulfurizing agent of copper or copper alloy parts and its process, it contains S 2%-10%, CuS 86%-95%, NH4Cl 2%, and Re 1%-2%; drying its powder, dehydrating, mixing and putting the powder and the parts in a sulfurizing box, placing the box in a heating furnace, preheating at 300 deg.C for 30-45 minutes, then sealing the box with flame resistant cement, preserving the heat at 500 deg.C-550 deg.C for 5-7 hours, and then cooling to room temperature with the furnace.
Description
Technical field
The present invention adopts pressed powder sulfurizing method the surface of copper and alloy part thereof to be carried out the technology of modification.
Background technology
Copper and alloy thereof have good physics and mechanical property, yet, the cost of copper and alloy thereof than higher, the life-span is shorter, has restricted its application.
Summary of the invention
The objective of the invention is to improve the wear resistance of copper or copper alloy part.
The present invention is the surperficial sulfurize permeating agent and the technology thereof of copper or copper alloy part, the consisting of of its penetration enhancer: 2%～10%S, 86%～95%CuS, 2%NH
4Cl, 1%～2%Re.
At first packed into copper or copper alloy part and ooze case in the oven dry of penetration enhancer powder, dehydration, mixing back, to ooze case and put into process furnace, preheating is 30～45 minutes under 300 ℃ of C, will ooze the case sealing with refractory cements then, be incubated 5～7 hours down at 500 ℃～550 ℃ again, cool to room temperature then with the furnace.
The granularity of penetration enhancer powder is 150～300 orders.
0.2～0.8 millimeter sulphide layer can be formed on the surface of copper or copper alloy part by above-mentioned processing, the wear resistance of copper or copper alloy part can be improved.
Embodiment
The present invention utilizes pressed powder sulfurizing technology to improve the characteristic on copper and alloy part surface thereof.Penetration enhancer consists of 2%～10%S, 86%～95%CuS, 2%NH
4Cl and 1%～2%Re constitute, and powder size is 150～300 orders.
Sulfurizing technology is: copper with penetration enhancer powder oven dry, dehydration, after mixing the back and cleaning through decontamination and alloy part thereof are packed into and are oozed case, will ooze case and put into process furnace, and preheating is 30～45 minutes under 300 ℃ of C, will ooze the case sealing with refractory cements then.Again 500 ℃～550 ℃ down insulations 5～7 hours, part cools to the furnace to come out of the stove after the room temperature and gets final product then.
The present invention adopts pressed powder sulfurizing technology to improve the wear resistance of copper and alloy part thereof.The advantage of this invention be easy and simple to handle, be easy to grasp, versatility is wide, no especial equipment requirements, production cost is low.
The present invention is used to produce wear resistance and the application scenario that can improve, enlarge copper and alloy part thereof, reaches free-revving engine energy-conservation, low-cost, special applications.
