Variation, by closely to remote, then from far near, in cycles, until spraying process terminates, in order to guarantee coating layer thickness, muzzle away from
It is more closer better from surface is sprayed-on, but excessively close then matrix temperature rise is too fast, causes disbonding, spraying fails, therefore in order to allow
Heat distributes more quicker, and to reduce matrix temperature rise, we, which take, proposes high-revolving method to reduce temperature rise and as early as possible acquisition foot
The ceramic coating of enough thickness, workpiece rotational frequency are adjusted to by original 80 revs/min: 150 revs/min；
4. heat control setting: because when inner hole thermal spraying, thermal spraying gun and to be sprayed-on at a distance from workpiece surface be to change, by
Closely to remote, then from far near, in cycles, until spraying process terminates, at proximal end, workpiece substrate temperature rises thermal spraying gun
Most fast, as distance becomes remote, temperature rise gradually eases up, therefore in order to guarantee to obtain the coating for closing symbol quality requirement, need to be to matrix
Temperature rise is tightly managed, and the mobile linear velocity of spray gun by original 0.3m/ minute, is increased to by we: 0.45m/ minutes, novel interior
Hole hot-spraying technique is applied in the spraying of eccentric cylinder inner bore (internal diameter 65mm, thickness of workpiece 26mm), in thermal spray process, partially
