Clearly to obtain：1) it after being handled conventional stainless steel by using the complex method of TIG welderings and laser melting coating, can obtain
The blade that average hardness reaches 1100HV is obtained, the hardness number of blade when significantly larger than using common stainless steel in the prior art
600HV；2) highest hardness difference only has 50HV between the different positioning of cladding layer in embodiment 1, and cladding layer in comparative example 1
Highest hardness difference can reach 305HV between different points, therefore, can not only be obtained using the method for invention and be swashed with conventional
The cladding layer of light cladding suitable hardness when handling, and the hardness distribution of entire cladding layer is more balanced, keeps the entirety of blade resistance to
It is more preferable to grind performance.
In conjunction with shown in Fig. 2 and Fig. 3, in comparative example 1 in the SEM shape appearance figures of cladding layer and comparative example 1 cladding layer SEM
Shape appearance figure is can be found that：Method using the present invention can obtain hard-particle powder and be distributed more uniform cladding layer, and right
It obtains hard-particle powder in ratio 1 to there are problems that being unevenly distributed in cladding layer, and TiC hard particles therein occur
Agglomeration influences the performance of entire cutter to lead to occur the defects of stomata and crackle in microstructure of surface cladding layer
And service life.
In addition, in carrying out the operating process of embodiment 1 and comparative example 1, pass through the energy work rate and cladding powder to using
The utilization rate at end carries out statistics discovery：1) energy used in embodiment 1 is the laser power of 1.5KW and the TIG welderings of 130A
Electric current is connect, and the laser power requirement used in comparative example 1 reaches 2KW, just can guarantee effective thawing to cladding powder；2)
By the calculating to cladding powder usage amount, 95% is reached to the utilization rate of cladding powder in embodiment 1, and in comparative example 1
In due to blade width very little, there is a large amount of powder directly to fall during powder feeding, effective cladding operation can not be carried out, melt
It covers powder using efficiency and there was only 78%.Moreover, needing progress in the process, repeatedly cladding processing just can guarantee final acquisition repeatedly
Cladding layer thickness.As seen from the above comparison, method using the present invention can not only substantially reduce to laser power and
The input quantity of bonding power reduces energy consumption, and can increase substantially the utilization rate and cladding efficiency to cladding powder, to
Cost is reduced, productivity is improved.
