The sintering-hot isostatic pressing process involves placing a
preform that has undergone molding or cold isostatic pressing into
the high-pressure vessel of a hot isostatic press, where dewaxing,
sintering, and hot isostatic pressing are performed separately to
bring the relative density of the workpiece close to 100%. This is
an advanced process following conventional hot isostatic pressing
technology.
Dewaxing (or using other forming agents) and sintering can be
carried out under vacuum or in a process-defined gas environment
(such as hydrogen, nitrogen-hydrogen mixtures), or under methane
protection. According to the traditional concept of sintering, both
liquid-phase and solid-phase sintering promote a reduction in
internal porosity of the sintered preform, resulting in shrinkage
and densification. During this process, sintering temperature and
time are parameters that must be precisely controlled. Hot
isostatic pressing further increases the density of the sintered
preform to approach the theoretical density value.
The briquettes undergo sintering and hot isostatic pressing within
the same furnace body (pressure air chamber). High pressure is
applied directly to the briquettes during the later stages of
sintering, which avoids the additional operations of cooling and
heating, prevents potential damage to the briquettes during
movement, and maintains stable temperatures during sintering and
hot isostatic pressing.
In hot isostatic pressing, inert gases such as helium and argon are
often used as the pressure medium. Because argon has a lower
thermal conductivity than helium (argon's thermal conductivity is
0.158 kW/m·K; helium's is 1.38 kW/m·K), using argon as the pressure
medium allows the furnace temperature in the working area to
quickly reach the required temperature and maintain a uniform
temperature distribution. Furthermore, argon is less expensive than
helium.
