Abstract
【解決手段】 少なくとも磨耗に曝される箇所を減圧中での処理によってコーティングした工具であり、コーティングは工具に直接堆積した少なくとも1種の硬質層と、前記硬質層に重ねた外側の少なくとも1種の摩擦低下層からなり、個々の層のコーンサイズは1μm未満の平均線幅を有する工具である。好ましくは、摩擦低下層のコーンサイズが0.1μm未満であり、硬質層が0.2ギガパスカルより高い圧縮内部応力を有し、硬質層が金属炭化物、金属窒化物、金属炭窒化物、およびチタン、ハフニウム、ジルコニウム、および前記金属と他の金属の合金からなる群より選択する。好ましくは、摩擦低下層は炭化タングステンのような金属炭化物と炭素を含んでなり、摩擦低下層の炭素分は61%より多い。
【選択図】 なし
Description
少なくとも磨耗に曝される箇所を減圧中でのPVD処理によってコーティングした工具であり、コーティングが、金属炭化物、金属窒化物および/又は炭窒化物から形成された、工具に堆積した少なくとも1種の硬質層と、無定形炭素を含有する、前記硬質層に重ねた外側の少なくとも1種の摩擦低下層とからなる形式のものであって;
摩擦低下層が硬質層に被さって配置されており、硬質層が1.1〜8μmの厚さ、および平均線幅1μm未満のコーンサイズを有し、摩擦低下層が、1μm未満のコーンサイズで0.12μm〜1.6μmの厚さを有し、摩擦低下層の全炭素分が61%より多く、摩擦低下層の金属炭化物が、クロム、ケイ素、チタン又はタングステンから成る金属の少なくとも1種から形成されていることを特徴とする工具。
16mmの直径とISO 1641/1タイプN.0110形状寸法を有する高速鋼S6-5-2仕上切削機の間で比較を行った。処理は充分に経時したアルミニウム合金Avional 100(AlCuMg1)の表面仕上とした。切削条件として、切削速度:240m/分、送り:0.3mm/歯、スリット深さ:16mmとした。3つのサンプルを試験した。
b)3μmのTiNで被覆 RA=9.1μm
c)2.3μmのWC/Cで被覆 RA=2.1μm
d)3μmのTiNと1.0μmの RA=2.1μm
WC/C(炭素72%)で被覆
(RAは平均粗さ値を表す)
WC/Cで被覆したサンプルc)は、10分後のオープンスペース上のコーティングの磨耗によって被覆していないフライス切削機に比較した長所がなくなり、即ちコーティングが消失し、4.1μmの平均粗さとなった。窒化チタンのみで被覆したサンプルb)は、未被覆のサンプルa)よりもなお高い粗さ値を示す。比較は、平均粗さで表した加工物の表面品質に関係する。
もう1つの試験において、ステンレス鋼の穿孔を試験した。使用したドリルは直径6mmの高速鋼42螺旋ドリルとした。選択した加工は、AISI316ステンレス鋼の深さ30mmの盲穴の穿孔とした。切削速度は6m/分とし、送りは旋回ごとに0.05mmとした。
