Description
Technical field
The invention belongs to the cutting working method of porous material, more particularly to a kind of method for turning of porous metals.
Background technology
With the development of porous metals technology of preparing, porous metals have obtained extensively should in industrial circle and people's life
With.And usually need for porous metal material to be processed as required shape and size using porous metals.
Porous metal material can carry out machining, such as turning, milling, grinding processing, but typically be difficult to out
High-quality surface, because the porous material after machining, the hole on its machined surface is easily blocked, so as to influence material
Gas permeability, reduces its performance or even causes workpiece to fail.Such as the bone implant of porous metals processing, surface blocks can not be made
Normal structure grows into implant；Additionally, the chip that machining is produced can be difficult to clean off into material hole, processing can be also influenceed
The performance of part.
At present, the method for JP20020043731 machinings foam metal, US2010/0312339 productions adds with cutting
To gather in hole after work implantation body method and implant, DE102011121688 (A1) machining for producing in the method
The medical treatment that collective is converted into the cutting working method of liquid or gaseous open-porous metal thing, US8323322 porous metals shape
The cutting working method of the porous metals of the document report such as implant and manufacturing process is first by porous metals base to be processed
Hole be filled curing process, specifically by easily except the material shape that is in a liquid state oozes porous metals base hole completely to be processed
Or porous metals base surface pore to be processed is only penetrated into, it is converted into its liquid state by phase transformation solid-state like, then by after solidification
Porous metals base carry out machining, the shape required for being formed with size, it is necessary to when, will be porous by phase transformation after processing
The easy of infiltration is removed except material is then converted to liquid or gaseous state in metalwork, is then cleaned.Due to packing material with it is porous
Intermetallic composite coating performance is different, and still there is a certain degree of pore plugging on the porous metals surface after processing, and experiment shows, the above method
The porosity that pore plugging is caused reduces average value and is more than 15%, can influence porous metal performance.
