Definitions

  • the present invention relates to a coated cemented carbide cutting tool insert particularly useful for turning operations in steels or stainless steels, especially suited for operations with high demands regarding toughness properties of the insert.
  • the cemented carbide insert has surface zones with element compositions differing from the bulk composition giving simultaneously an excellent toughness performance and good resistance to plastic deformation.
  • High performance cutting tools must nowadays possess high wear resistance, high toughness properties and good resistance to plastic deformation. Improved toughness behaviour of a cutting insert can be obtained by increasing the WC grain size and/or by raising the overall binder phase content, but such changes will simultaneously result in significant loss of the plastic deformation resistance.
  • a coated cemented carbide insert with a 10-30 ⁇ m, thick essentially gamma phase free and binder phase enriched surface zone with an average binder phase content (by volume) in the range 1.2-2.0 times the bulk binder phase content.
  • the gamma phase consists essentially of TaC and TiC and to some extent of WC dissolved into the gamma phase during sintering.
  • the ratio Ta/Ti is 2.0-3.0.
  • the binder phase is highly W-alloyed.
  • the CW-ratio takes a value ⁇ 1 and the lower the CW-ratio is the higher is the W-content in the binder phase. It has now been found according to the invention that an improved cutting performance is achieved if the CW-ratio is in the range 0.80-0.85.
  • the present invention is applicable to cemented carbides with a composition of 5-12, preferably 9-11, weight percent of Co binder phase, and 3-11, preferably 7-10, weight percent TaC + TiC and a balance WC.
  • the Nb content should not exceed 0.1 weight percent.
  • the weight ratio Ta/Ti should be 2.0-3.0.
  • the WC has an average grain size of 1.0 to 4.0 ⁇ m.
  • the cemented carbide body may contain small amounts, ⁇ 1 volume-%, of ⁇ -phase (M 6 C).
  • Inserts according to the invention are further provided with a coating consisting of basically 3-12 ⁇ m columnar TiCN-layer followed by a 1-8 ⁇ m thick Al 2 O 3 -layer deposited e.g. according to any of the patents US 5,766,782, US 5,654,035, US 5,674,564, US 5,702,808 preferably with a ⁇ -Al 2 O 3 -layer and preferably with an outermost thin layer of TiN which preferably is removed in the edge line by brushing or by blasting.
  • a cemented carbide insert produced according to the invention is provided with a coating consisting of: 6 ⁇ m TiCN, 5 ⁇ m Al 2 O 3 and 1 ⁇ m TiN. This coated insert is particularly suited for cutting operations in steel.
  • a cemented carbide insert produced according to the invention is provided with a coating consisting of: 4 ⁇ m TiCN, 2 ⁇ m Al 2 O 3 and 1 ⁇ m TiN. This coating is particularly suited for cutting operations in stainless steels.
  • Cutting inserts according to the invention comprising a cemented carbide substrate consisting of a binder phase of Co, WC and a gamma phase from the elements Ta and Ti with a binder phase enriched surface zone essentially free of gamma phase and a coatings are made in the following way.
  • a powder mixture containing 5-12, preferably 9-11, weight percent of binder phase consisting of Co, and 3-11, preferably 7-10, weight percent TaC + TiC and a balance WC with an average grain size of 1,0-4,0 ⁇ m, preferably 1,5-3,0 ⁇ m is prepared.
  • the Nb content should not exceed 0,1 weight percent.
  • the weight ratio Ta/Ti should be 1,0-4,0, preferably 2,0-3,0.
  • the raw materials are mixed with pressing agent and possibly W such that the desired CW-ratio is obtained and the mixture is milled and spray dried to obtain a powder material with the desired properties.
  • the powder material is compacted purview of the skilled artisan to determine whether the requisite surface zone of the cemented carbide have been obtained and to modify the nitrogen addition and the sintering process in accordance with the present specification in order to obtain the desired result.
  • the raw materials are mixed with pressing agent and possibly W such that the desired CW-ratio is obtained and the mixture is milled and spray dried to obtain a powder material with the desired properties.
  • the powder material is compacted and sintered. Sintering is performed at a temperature of 1300-1500°C, in a controlled atmosphere of about 50 mbar followed by cooling. After conventional post sintering treatments including edge rounding a hard, wear resistant coating according to above is deposited by CVD- or MT-CVD-technique.
  • Inserts from A, B and C were tested with respect to toughness in a longitudinal turning operation with interrupted cuts.
  • the inserts from A and C were tested in a three turning operations with high toughness demands due to interrupted cuts.
  • the inserts were run until breakage of the edge.
  • the insert style SNMG120412-PR was used.
  • Examples 2, 3 and 4 show that the inserts A according to the invention exhibit much better toughness in combination with somewhat better plastic deformation resistance in comparison to the inserts B and C according to prior art.
