Abstract
The invention discloses 2~4 parts of 4~10 parts of 3~4 parts of 6~10 parts of 9~14 parts of parts by weight aluminium powder, comminuted steel shot, lead powder, copper powder, the manganese powder and 3~5 parts of silica flour of a kind of wearable hard alloy, including following components.Wearable hard alloy provided by the invention improves the anti-wear performance of hard alloy due to adding aluminium powder, comminuted steel shot, lead powder, copper powder, manganese powder and silica flour, while has excellent thermal fatigue and shock resistance damage capability, has resistance to broken, corrosion resistant performance.
Description
Technical field
The present invention relates to antifriction alloy field, more particularly to a kind of wearable hard alloy.
Background technology
Hard alloy is applied to a variety of occasions as main raw material(s), such as rotary drill hard-metal insert, is using process
In failure mechanism for heat fatigue with abrasion simultaneously effect result, in order to meet such use occasion, it is desirable to hard alloy
There is good thermal fatigue and wearability simultaneously.
Traditional hard alloy is generally homogeneous texture, often wear-resisting to sacrifice its when improving the thermal fatigue resistance of product
Property is cost；Conversely, when needing to improve the wearability of product, again must be such to sacrifice its thermal fatigue resistance as cost
Alloy is difficult to obtain good combination property.
The content of the invention
It is an object of the invention to provide a kind of wearable hard alloy.
The purpose of the present invention is achieved through the following technical solutions：
A kind of wearable hard alloy, include 6~10 parts of 9~14 parts of parts by weight aluminium powder, comminuted steel shot, the lead powder 3~4 of following components
Part, 4~10 parts of copper powder, 2~4 parts of manganese powder and 3~5 parts of silica flour.
The parts by weight of above component are put into crucible furnace, mould is poured into after using temperature as 500~550 DEG C of high temperature melt
It is cooled and shaped in tool.
Wearable hard alloy provided by the invention carries due to adding aluminium powder, comminuted steel shot, lead powder, copper powder, manganese powder and silica flour
The anti-wear performance of high hard alloy, while there is excellent thermal fatigue and shock resistance damage capability, have resistance to broken, corrosion-resistant
Performance.
