複数のコーティングされたピストンリングを形成する方法
Document Type and Number:
Japanese Patent JP6408994
Kind Code:
B2
Abstract:
A method of coating all surfaces of a plurality of piston rings in a single run by a chemical vapor deposition (CVD) process is provided. The method can include providing a coil formed of an iron-based material; heating the coil; and depositing a coating on all surfaces of the coil during a single continuous period of time, without having to move the coil during the CVD process. The coil is maintained in a fixed position during the depositing step. The method next includes splitting the coil into a plurality of separate coated piston rings. Alternatively, the method can include providing a plurality of stacked keystone piston ring bodies; and disposing a cylinder around the stack to maintain the keystone piston ring bodies in position while depositing the CVD coating on all surfaces of the keystone piston ring bodies during the single coating run.
