The invention discloses a
rubber tapping machine blade, a preparation method thereof and an automatic
rubber tapping machine, and relates to the technical field of
natural rubber tapping. The
rubber tapping machine blade comprises a blade base body, a bonding layer, a
transition layer and a functional layer, the bonding layer, the
transition layer and the functional layer are sequentially arranged on the surface of the blade base body, the bonding layer is a TiAlN
coating, the
transition layer is a TiSiN
coating, and the functional layer is a TiBC
coating or a TiBCN coating; wherein the content of C in the TiBC coating is greater than 0 at.% and less than 20 at.%; the content of C in the TiBCN coating is larger than 0 at.% and smaller than 20 at.%, and the content of N in the TiBCN coating is larger than 0 at.% and smaller than 10 at.%. The bonding layer, the transition layer and the functional layer can be prepared through arc
ion plating; the rubber tapping machine blade is excellent in abrasion resistance,
corrosion resistance, hydrophobicity and sharpness retentivity, low in
friction coefficient and suitable for the automatic rubber tapping machine, the sharpness retentivity of the automatic rubber tapping machine blade can be effectively improved through the
composite coating, the service life of the automatic rubber tapping machine blade can be effectively prolonged, and the rubber tapping effect of the automatic rubber tapping machine can be effectively improved.
