Comparative example
The cutter processed using the method for the prior art.
Testing result and analysis
Salt spray test is carried out to the cutter that the obtained cutter of above-described embodiment 1-5 and comparative example obtain, to detect cutter
Corrosion resistance, and carry out tool surface coating ROHS detection, with detect four heavy metal species content (examination criteria requirement:
Lead content < 1000ppm, cadmium content < 100ppm, mercury content < 1000ppm, sexavalence lattice content < 1000ppm), as a result such as table 1
It is shown.
1 salt spray test of table and ROHS testing result
Seen from table 1, using the corrosion resistance of the method detection cutter of salt spray test, embodiment 1-5 is obtained after test
Cutter do not occur phenomenon of corroding or get rusty, and there is rust staining in the cutter that comparative example obtains.Show that processing method of the present invention obtains
To cutter all have preferable anticorrosion and rustless property, use more safety and sanitation.In addition, for the detection knot of heavy metal
Fruit shows that the cutter content of beary metal that 1-5 of the embodiment of the present invention is obtained reaches examination criteria requirement, and lead content and sexavalence lattice
Content is substantially less than the analog value of comparative example, therefore the cutter that processing method of the present invention obtains is more environmentally-friendly, and can trust makes
With.
In addition, the Tool monitoring surface roughness obtained to the obtained cutter of embodiment 1-5 and comparative example is (with GB1038-
1983 be reference) and bacterial adhesion index.Bacterial adhesion index is using the value of comparative example Tool monitoring as unit 1, each embodiment knife
Tool detection obtains bacterial adhesion index of the amount of bacteria with the ratio of the amount of bacteria of comparative example Tool monitoring as the corresponding embodiment.
The results are shown in Table 2.
2 testing result of table
As can be seen from Table 2, compared with the cutter of comparative example, cutter table that 1-5 method of the embodiment of the present invention is processed
